Amazing sounding speaker. With deep bass, extended treble, sounding so real and sensitive. 

Tried for the first time today with the Pleiades BD650.

Only possible problem may be some king of mid high emphasis, by ear it sounds happening at around 4KHz. If this is the case it may be corrected with an inductor in series and a resistor or capacitor in parallel with said inductor, see older euroelectron posts on equalizing full range speakers

Blue Velvet

 At your risk.

Today in Athens there is a kind a heat wave. About one hour ago while walking towards the National Library this song was being played at the outdoors cafe. 

While listening on my way I thought it can be heard how good singers build the note sung by increasing the pitch by glissando after attack until it sounds correct to the listener's mind.

The song was inspired by a woman wearing a blue velvet dress at a party watched  by songwriter Bernie Wayne.

Pleiades BD650 one Darlington transistor power amplifier in single ended Class A

 At your risk. A suitable fuse must be in series with any battery for safety. Protect your ears from high SPL. There is a broadband click sound when turning off the amplifier.

It sounds very nice. Drums sound like the real thing.

Singal path: 

On the Border - Al Stewart (on origianl CD) - Sony CD Walkman line out - Marantz Imperial 5G (one speaker so far)

Power supply is just 12V from a 1.3AH lead acid battery. 

Ic is 120mA. So power output should be less than 1W.

Output hand wound transformer is about 3 to 1. So from an 8 ohm speaker the amp sees about 

8 ohms x 3 x 3= 72 ohms. Air gap is by gluing one layer of scitch invisible tape across the stacked Es.

The transformer used on this prototype is rather big.

Bias is by a resitor from collector to base.

There is a 50uF film wound input capacitor.

And a variable series resistor (rheostat)  connected to base for volume control.

It should be nice making 2 such monoblocks inside a transparent plexiglass box powered by 8 AA batteries in series with a suitable fuse.

For example taking 4 ply linoleum sheets of 2.5mm thickness each and glueing them together with PVA.

Then mounting a woofer and tweeter. Connecting and inductor in series with woofer in order to reduce mid heaviness and a capacitor in series with resistor in series with tweeter until A Woman in Love - Barbara Streisand sounds like listening to the Sennheiser HD-580 headphones.

Hopefully the panel used as speaker baffle acts also as membrane bass absorber.

Definition of Musician?

 At your risk.

A person who can sing or play at least one note correctly.

It seems a musical note have to be increased in pitch after the attack of the note ie on sustain. Otherwise it sounds flat to the listener's brain.

Speaking to one person when giving a lecture or writing a book, paper etc

 At your risk.

It helps to do away with stress, anxiety. You think you play for example music to just one person.

I think I leaned this from BBC producer Malcolm Love when he lectured at the British Council in Athens.

What does this resistor do above transistors, electronic valves or electron tubes, JFETS etc?

At your risk.

It was a mystery to be when being a kid. I was building those amazing sounding simple class A amplifiers but at |I did not know.

Then at Warwick University the great lectures of Dr. Neil Storey showed us that this resistor changes the variable current to variable voltage ie the music signal itself. We learned so much about this load resistor, load lines etc.

Matti Otala, Transient Intermodulation Distortion

At your risk.

I fondly remember reading papers by Matti Otala on how a transient (music) can make a feedback amplifier distort 100 per cent until negative feedback has time to arrive at the input leaving the amplifier at the very high open loop gain!  

https://www.diyaudio.com/community/threads/matti-otala-an-amplifier-milestone-dead-or-alive.125541/

On an AES conference in 1973, Dr. Matti Otala presented a paper describing the design of a TIM-free audio amplifier...

Update to Pleiades 3 K117 RIAA battery powered phone preamplifier

 At your risk.

Now that it is inside a nice aluminum box, frequency response tests are being made using an inverse RIAA network by Lipshitz.

There was +3dB at mid bass!

-20dB at 20KHz!

It looks like the high impedance 470K pot loaded by the input capacitance of the JFET creates this high cut.

So almost like cheating the 100 Ohms resistor was changed to 12K.

Now we have -3dB at 20KHz. There is about +1.5dB at 4KHz.

For correcting the mid bass heaviness 15nF was changed to 20nF.

Now mid bass is flat and we have -3dB at 20Hz.

Even before the changes the preamp sounds very good with a feeling of 2 octaves above CDs, YouTube videos etc. After the changes about 3 octaves higher treble sparkle and no bass heaviness.

What I do like about  the sound of this preamplifier is the smoothness of the treble on violins. I think this is achieved by the fact that there is no negative feedback, no active negative feedback filter but a passive instead. So transients will not instantaneously clip (see Matti Otala transient intermodulation distortion papers).

I also like  that each stage is at low gain so there is headroom at the input.

Expanding Time

Ai reply:

which microphone was used for recording patsy cline?

Patsy Cline's legendary Nashville studio recordings were primarily captured using the Schoeps M201 condenser microphone. [1, 2]

The Primary Studio Microphone

While famous singers of her era frequently used the Neumann U47 or Telefunken U47, producer Owen Bradley chose a different path at the famous Bradley Studios (The Quonset Hut). Photographic archives from the Country Music Hall of Fame and Museum capture Patsy standing in front of this specific German-engineered mic during the sessions that defined the "Nashville Sound". [1, 2, 3, 4]

Key Details About the Setup

• The Microphone Model: The Schoeps M201 (introduced in 1952) was a high-end, small-diaphragm tube condenser microphone. It featured a distinct thin, rectangular extension arm that allowed it to look somewhat like a ribbon microphone from a distance. [1, 2]
• The Sonic Character: The Schoeps M201 was celebrated for its pristine, transparent, and ultra-smooth frequency response. This perfectly complemented Patsy's immense vocal power, rich lower register, and emotional dynamics without pushing her voice into harshness. [1, 2]
• The Room Dynamic: At the Quonset Hut, instruments and backing vocalists (like The Jordanaires) were recorded live together in the same room. The microphone's natural capture allowed Bradley to use minimal processing, relying instead on physical placement to create the warm, haunting depth heard on masterpieces like "Crazy" and "I Fall to Pieces". [1, 2, 3]

If you are interested in vintage studio gear, I can provide more details about how Owen Bradley's Quonset Hut studio was set up, or dive into the recording process behind her signature song, "Crazy."

Home Making a great beer?

At your risk. This is not a medical or nutritional advice.

I do not know if this is beer but it tastes great. Now that the temperature is higher it deteriorates quicker, in less than 48 hour preparation.

Please see net post on the updated Pleiades meal.

Pleiades Meal Update

 At your risk. This is not a medical or nutritional advice.

Soaked in filtered water for 48 hours selected (checked for small hard for teeth objects) barley seeds. Funnily enough the water after 48 hours tastes like a great beer. But now in summertime with higher room temperature at 48 hours it has deteriorated.

Then adding 2 teaspoons of whole grain tahini. Great taste.

Then 100 per cent cocoa powder. Great taste.

Then 1 royal date for sweetening and even greater taste.

Can this be made to a chocolate bar? Will it also work with oat flakes?

Harris from Effectum Electron

 At your risk.

I had the pleasure seeing again Harris from the very nice electronics repair and construction shop Effectum Electron in Athens:

https://www.effectum-electron.com/

I was telling him about the Pleiades electron tube pre preamplifiers with one electron tube operating with a 3.6V (3 1.2V batteries in series). The schematic should come if one Google searches with keywords Pleiades Amplifier Schematic. I was also telling him about the Pleiades DLxx or EL84, or EF183 triode connected single electron tube power amplifiers with a step up input transformer instead of a driving electron tube. Also the Pleiades power amplifier with no capacitors or resistors just one battery for heaters, one for Anode supply, one for bias, one input and output transformer and how nice they sound.

I was very pleased to see how tidy his lab is. He is making a single ended electron tube power amplifier on a very nice green painted chassis. It is so refreshing walking in your hometown, New Smyrna and an intelligent person is up to building a nice single ended electron tube amplifier.

On increasing the microphone distance to record a much better vocal, reply to Eleni, Vasilis. Σχετικά με πιο σωστή απόσταση μικροφώνου από την πηγή φωνής

At your risk.

Eleni and Vasilis were doing alive PA rehearsal outdoors. It was suggested that Eleni increases the vocal mic distance from 1in to more than 3in. The sound opened up, there was treble detail and Eleni sung much closer to in tune, (her pitch increased much closer to in tune).

Here is the reply to the them:

Το μικρόφωνο δεν πρέπει να κοιτάει προς το στόμα αλλά προς τη μύτη ή το κεφάλι σύνήθως απο ψηλά.

Όταν τργουδήσατε σε διπλάσια απόσταση αμέσως ακούστηκε καλύτερα γιατί τα περισσότερα μικρόφωνα είναι κατασκευασμένα για παράληλα μέτωπα ηχητικού κύματος και όχι σφαιρικά [!]. Στη διπλάσια απόσταση μειώθηκαν μόνο τα μπασα (proximity effect) και έτσι αναδειχτηκε το λαμπερό μέρος της φωνής. Και για λόγο που δεν ξέρω ακόμη η φωνή ήταν πολύ λιγότερο χαμηλή από τον σωστό τόνο.

Την ώρα που ηχογραφούσατε, το μικρόφωνο είταν πιο κοντά απο διπλάσιο και χάλασε λίγο ο ήχος αλλά δεν ήθελα να σας διακόψω.

Κανονικά ένα κατευθυντικο μικροφωνο ακουγεται σωστά (επιπεδη καμπύλη απόκρισης ως προς συχνότητα) σε απόσταση πάνω απο μισό μέτρο. Το ύπαιθρο είναι ειδανικό γιατι εκεί δεν έχουμε εκατομύρια καθυστεριμένες ανακλάσεις του ήχου που καταστρέφουν το αποτέλεσμα σαν θολωμένο είδωλο.

Καλή συνέχεια Βασίλη και Έλενη.

Notes:

To my mind when I listen to it with the Sennheiser HD-580 headphones, it sounds bass or mid bass heavy. The Shure Unidyne B may do the trick as in my experience it can sound with flat frequency response from my mind as producer to my mind as listener without the need to add a frequency response EQ or filter after the microphone.

We need to use a much quieter outdoors place.

The Principle of Least Change in Music

(At your risk).

Least change has great impact on mind perception.

For example:

You Do Something to Me - Paul Weller

The song is written in E minor.

So the first bass is E.

Paul sings E #F G B while bass is E.

Then repeats B while bass goes down to D creating an interval of major 6th.

Then bass goes down to A but as there is nothing at that moment sung the mind of the listener has the perception of prepared major 9th since the distance between bass A and melody B is 9 steps of the scale.

For more please read the book: "A Letter to Clive Davis" - euroelectron

Further reading:

The Bach Manual for his students in composition which can be found at the appendix of Bach's biography by Spitta. I do not know if it is included in newer editions, please check.

The major 3rd major 7th Chord

 

For example.

Bass C (Do) and a higher part playing B (Si).

Accord to the Bach-Niedt manual we also add the 3rd with respect to bass, that is E (Mi).

The beauty can be heard whenever the singer sings "I can't" in every chorus of the song We Are the People - Empire of the Sun.

The Kid and the Fish, a hypothetical fairytale

 (At your risk).

The kid goes at the sea bank to buy fresh fish for the cat.

All fish are dead except 1 which jumps with agony inside an open white EPS box.

The fish cries please save me, buy me and set me free in the nearby sea.

He decides to buy 2 fish for the cat and him for 5e and then he asks the price for the alive fish.

OK 5e but please do not peel it and let me take it buy the time I leave.

The assistant of the seller puts the living fish just inside a supermarket strong plastic bag.

The boy rushes to the nearby beach at the back of the market place when he is alone with the fish in hand.

He throws the fish into the sea!

The fish is kind of dizzy. Almost does not not move.

A seagull immediately comes to get the fish.

The kid is ready to jump to save the fish or to get something form the beach to throw to the seagull.

The seagull gets frightened and leaves higher in the air.

The fish starts moving but there are a few dozens small fish gathered ready to eat it.

But as the fish starts turning towards them they get scared and kind of withdraw.

The fish find itself at very shallow water, almost eating mud.. 

But gets stringer and stronger and ...

Suddenly starts moving towards deeper water, leaving.

Salutes the kid...
