Influence of DC offset on bias


Hi everyone. I'm usually an observer here and hopefully learn something along the way. Can someone shed some light on my question of what if any influence or affect dc offset has on the bias of an amp. I know how to check both and have never come across an amp with identical offset on both sides; well within acceptable levels on both sides, but never the same. Also impossible to adjust them to the same level. Does this render identical bias on both sides incorrect in terms of channel balance as it affects your ears? I would greatly appreciate some insight into this.

Thank you

I'm referring strictly to SS. Amp has both offset and bias pots. I understand anything up to 50mv offset on each channel is acceptable, 0 being ideal. However, the best I can get is 16mv on the left, 26mv on the right. Bias set at 150ma on each channel. My question is, does the stilted offset skew the bias adjustment? I could just change up the left channel offset to match the right, but not all SS amps have offset pots. I have others with dc servo control and still others with discreet components for the offset but they are never identical on both channels either. So I guess what I want to know is should there be a bias compensation on either channel to accommodate the difference in offset?
Are you sure that you can play around with bias adjustment in SS amp?
In most of the SS cases I would strongly recommend not to adjust.
The pots are there for that very purpose. Channel balance depends on quiescent current being equal in both channels. But my question addresses exactly that issue. Must it be equal or adjusted relative to offset for each channel in order to achieve an equal end result at the speakers?
Hifihvn,
In transistors it's the same story only make plate equivalent to collector(assuming connection with common emitter). There's a purpose to adjust the offset so the output is measured the same across collector and ground on both opposite junction transistors pnp,npn pair (I assume that it's a class B amplifier, but I might be wrong) and another channel accordingly. So the offset might be different in transistors (they're way harder to match than tubes and have larger parameter tolerance) but bias current will be the same and 'sound' the same.
Can you tell what kind of amplifier we're talking about?
Brand? Class of operation? Must be a very vintage one. Most of the current ones would have an auto-bias which is a piece of cake to implement.
