Recapping and Bias


Hi,

I’ve recapped a few cheaper things I have, and with good results. I see that recapping is something a lot of people do. But I’m a hobbyist, and I probably don’t know most there is to know. I notice bias is mentioned a lot in regards to servicing amps, but I can't find any information about it regarding recapping.

1) Should you check the bias after recapping on SS amps/gear?
2) If there is no pot for this, would you worry?

I’m especially thinking of newer gear, made just now or during the last 10 years.

First, if there's no bias adjustment then don't add one. Second, recapping will not affect bias. Bias is a voltage and caps don't affect voltage. Resistors do that. Not caps. Finally, when recapping you must use equal value, because otherwise you can screw up frequency response. So I've lost count, but that's like 4 different ways you don't need to worry about what you're worried about.
