Hi @REK2575 it's a pity the answers to your question are all a bit confusing!
You have, however, been given some very helpful advice. I think, for example that @sergeauckland gave a clear explanation in Post 15
This comes up quite a lot on ASR and other forums, so to reiterate in bold underlined: the position of the volume knob has no meaning. Why? :

This comes up quite a lot on ASR and other forums, so to reiterate in bold underlined: the position of the volume knob has no meaning. Why? :
- Volume controls are often "logarithmic" potentiometers which means their resistance doesn't come down by a fixed resistance with every degree of rotation but has small variation at the start and large variation at the end. As you rotate clockwise going a further 5 degrees beyond "midnight" has a bigger effect than going 5 degrees beyond "9PM"
- How much you need to turn the volume control depends on how much voltage the preamplifier sections sends out at max - if it's a not a lot (e.g. 1v), you may need to turn further, if it's a lot (e.g. 10V) you may not be able to turn the volume control much above "9PM"
- How much you need to turn the volume control depends on how much voltage the power amplifier section needs to see to be at max. If it needs a lot (e.g. 12V) to get to max volume, you may need to turn the volume control past "3AM". if it needs a little (e.g. 0.5V) you may not be able to turn the volume control much above "8PM".
- How much you need to turn the volume control depends on the gain of the power amplifier section. If it has not much gain (e.g. 10dB), you may need to turn the volume control past "2AM". If it has a lot of gain (e.g. 40dB) you may not be able to turn the volume control much above "10PM".
