Nobody can hurt you if you do not want it too. Κανεις δεν μπορεί να σου κάνει κακό αν δεν το θες και εσύ.

At your risk. Με δική σας ευθύνη.

By Lambros.  Λάμπρος.

Lambros had given me the book of philosopher Epictetus called Enchiridion, manual of living. Ο Λάμπρος μου είχε δώσει το βιβλίο του φιλοσόφου Επίκτητου με τίτλο Εγχειρίδιον.

Delay on voice is very important

 At your risk.

For example.

A Woman in Love - Barbara Streisand

The Year of the Cat - Al Stewart

Listening carefully one can realize that together with the direct signal of the vocal there is a delayed in time version added.

This can be done in many ways.

An echo chamber does it automatically as it takes time for sound to travel from the speaker to the microphone inside the sound reflective room.

By the way cylindrical pipes like for example drain pipes standing on floor can make the reverberation sweeter possibly due to diffusion scattering of the ways. If memory is correct having seen photos on the Abbey Road book, the echo chamber i think has such or similar scattering structures.

 

How to create an airgap in an output transformer for single ended power amplifiers?

 At your risk.

The Es can be stacked together. The Is are stacked together.

For example Scotch invisible tape can be placed on top of the Es before placing next to them the Is.

When there is DC current flowing in the winding of a transformer, an airgap can prevent magnetic saturation and even increase incremental inductance/

Reading the small letters on food or beverage packaging

At your risk.

This is not a medical or nutritionist advice.

For example some beverages contain taurine which as fear as i know is a male hormone and these beverages can be seen to be drunk even by very your women.

Or for example cheap cookies or croissants that may contain hydrogenated palm oil (margarine?) which have a reputation or clogging arteries.

On the other hand I had been told told many years ago that sesame seeds or tahini, (made from sesame seeds) is a very good food that keeps arteries and health in great shape. The oil is good quality naturally produced from the sesame seeds. I still eat tahini, every day, see the Pleiades meal or earlier posts/

Is coffee bought in cafeterias contaminated with egg yolk powder?

 At your risk.

This is not a medical or nutritionist advice.

I do not know.

I heard in public transport that a cafeteria in Athens had been closed down in the past as it was found that they were using egg yolk in order to make the coffee velvety creamy etc.

Deaths for example from heart attack or clogged arteries were experienced in the area before there was an order to check the cafeteria for substances that may increase bad cholesterol. 

Hopefully modern cafeterias...

Update to Pleiades 2N3053 stereo single ended zero feedback power amplifier in class A operation

 

At your risk.

Class A operation means that electrons flow trough the active device (transistor in this case) all the time.

Here are some updates.

The two 1.2Ah 12V batteries were moved to the smaller bedroom.

Signal path:

Brothers in Arms - Dire Straits on un remastered CD - SonyD-EJ758CK CD Walkman line out - Celestion Ditton 150

Great, amazing sound.

Current for both channels was measured to be 32mA, due to higher temperature in Athens.

By chance only one 12V battery was then connected and the sound was even better, more easy and smoother. Current was just 14mA for both channels.
