Can anyone give me the spec for bias current on a 2226B? Also, here's a picture of the amp board can anyone ID the bias and offset trimmers for each channel? Thanks.

Bump,
Nobody has a service manual they can look in for me?

I don't have one. Have you tried to find one? I am sure that you have, but they must be scarce if no one has one.

Jim, the thing works perfectly. I hate to buy a service manual just to set the bias and offset.

Tony, that was just the information needed. The bias and offset came right into spec. Thanks for the post.

I bought a 2226 last night. Would the same apply to it as the 2226B, as far as
the three voltage checks and adjustments above?

I don't know what changed with the B version. Take a look at the picture of the amp board in the first post. Does the amp board in the 2226 look that that one? If so, it's a good bet the procedure is the same.
