A melody dreamed

Key is C sharp major but we will use C major to define it. o o o o o o D - E - - - - - E - F - - F F G A (3) G - - - - - E - F F F (3) F G A (3) G - - - E - D - C - - - - - - - D - - - - - - - A - - - - - - G G - - - - - repeat (verse) 1st chrord is bass C, then bass C with C F A, then back to Cthen again C with F major then A minor then D major then G bass with D major resolved to G major. A woman was singing in the dream and a rock band was softly playing.

Eureka, A class A power amplifier for music with just an electron tube, no capacitors, no resistors, no feedback, just a centre taped input transformer, a centre taped output transformer and 3 battery supplies

At yoyr risk. Please add Abba or Mike Oldfield type varispeed on previous post on recording vocals. Singnal is fed to 1 to say 10 input transformer. Secondary is connected to each grid of a say ECC84 electron tube. Centre tap is connected to minus of say 4 volts coin battery (Vc) for bias. Positive terminal of battery to the 2 cathodes. Primary of the output transformer say 6Kohms to 8 Ohms to the 2 anodes. Centre tap to possitive say 150V from batteries in series in series with fuse. Negative of this Vb supply to the 2 cathodes. Va supply from a batterry of say 6 volts in series with fuse to heaters. That's all folks. This is the Pleiades push pull or differencial single electron tube (2 in one bulb) only audio power amplifier. Enjoy!

Eureka, How to get an amazing sound out of any good dynamic microphone

At your risk. With a descent singer it should be possible to get that Broken Wings-Mr. Mister or for example Frozen-Madonna sound quality. 1. Great acoustics meaning no early reflections, for example outdoors, large tall spaces, broadband sound absorbers (elastomer panels for bass reflection absorption)etc. 2. Mic 12" away from singers head, facing singer's head at say 45 degrees from above. 3. Connecting in parallel with mic output (voice coil) 2 electrical Pleiades filters. An inductor of say 230mH (82mH for an omnidirectinal mic) as a low cut filter to cut bass heaviness in reproduced voice. The second filter in parallel is a Pleiades (130ohm,20mH) ie an inductor of 20mH in series with 65Ohms in series with 65Ohms as a high pass filter at a high frequency with gentle slope in order to produce this amazing voice sparkle. 4. If the Lou Burroughs (Electrovoice) trick of using 2 omni mics out of phase and singing to one of them is used then the low cut filter can be ommited, mic to mic distance will adjust the low cutoff frequency (typically a few inches). 5. Monitoring with good large loudspeakers (for example Celestion Ditton 150) in order to hear those bass difects and correct them, (my humble opinion is that on headphones these problems so common on so many productions cannot be effectively heard, same for small speakers. Enjoy! Enjoy!

Why EUREKA, nothing new discovered, Pleiades 2N3053

At your risk. It sounds fantastic. Even with a small output transformer althought at preliminary comparison the bigger Sowter SK05s may be better. Small size, small weight, in class A (electrons flowing all the time and dancing to music. It works well with different kind of loudspeakers. Althought less than one Watt it can fill a large room with comfortable great sounding music. No class B crossover distortion. No complicated phase spitter for push pull. No driver transistor needed, since the power transistor operates at low current, and output transformer steps this current up. Impedance matching for maximum power transfer done by output transformer. No complicated PSU, regulators etc, internaly chacing up the music signal needed. As simple as it may get, just one transistor, one bias resistor, one output transformer, one coupling capacitor, 2 12v batteries etc in series with a fuse. Pure class A with low power consumption. Small size, small power output, big sound with a bigish loudspeaker, (big cabinet compared with drive unit having a low reasonance frequency, deep bass, amazing mid, treble. Depth of sound, musicality and smooth detail, smothness. No negative feedback chassing up the music signal needed, no slew rate problem, no crest factor problem... Gradualy increasing low order harmonic (non linear) distortion as output signal increases, ie at high level. Distortion tends to 0 as signal tends to 0 (for example when signal passes throught to x axis, just like real musical instruments. Just like nature.

Eurika, even a small (air gaped?) transformer can be used on the Pleiades 2N3053 single transistor power amplifier

At your risk, including all other posts, my appologies if any of all these public domain posts are or are interpreted as being offending. A small Grundig BV 9054-339.02 output transformer has been used at such low power consumption or power output much less than 1 Watt and the sound is still big with deep bass, great mid , great delicate, extended treble as expected from a class A (electrons flowing all the time) amplifier. Signal path: CD single Crush - Jennifer Page - Sony CD Walkman line out - Pleiades 2N3053 single transistor power amplifier with small Grundig output transformer, Vb=24V - Fostex FE127E speaker in Pioneer CS-353 cabinet facing ceiling in large living room - listener at about 2 meters in any direction.

2 omni microphones for Left, Right and an out of phase omni mic for noise, bad acoustics canceling

It works. Signal path: Beyer M55 to L input, Beyer M55 to R input, out of phase Beyer M55 to (L+R ie Mono input) - UHER Mix 700 Stereo Mixer ie Adder - Sennheiser HD-580. Alernatively hybrid transformer(s) can be used connected directly to the microphones. The great trick found in (Microphones - Lou Burroughs) book can even be used for a binaural or stereo recording.

The best revenge is be seen having a great time

At your risk. Or having a great time. (I kaliteri ekdikisi ine na pernas kala). Quote from a prince communicated by Michalis.
