Slightly mismatched channels

[lumpylipton]

Hi,

My Pearl has been working for a good month now, and sounds great. However, I've noticed that one channel is just a touch quieter than the other. I did use matched transistors, however, it seems one channel is still not quite matched close enough.

Is there a "simple" way to just get a db or 2 more gain. I've been reading other posts on changing the value of R19.

Any guidance would be appreciated...I don't really relish removing all the transistors, ordering some more and trying for a tighter match.

Thanks!
Warren
