Bias adjustment in an amp....need advice from the techs
I have an older model Yamaha receiver (one of the better ones) and I noticed a couple of little riostats or potentiometers right next to the output transistors (seems to be one for every channel) and wondered if this is the bias adjustment? or maybe a gain level? I dunno, I was hoping to catch a tech on this site and find out if it can be beneficial to adjust these in any way. Thanks for any advice!
Put this on the PE tech forum
There are quite a few EEs that frequent the site and will be able to provide you with more info. Regards, Paul.
