    All the filter caps should be replaced including the bias caps. You may have issue down the road. It is not a bad job it works. The power supply is big part of these amps.

    FYI: if your EQ pedal is the MXR 6 band pedal, they are noisy as heck when you move the top band(s) (3.2khz I believe, or maybe 1.8khz) above the middle position, and are noisy even if you don't. That's why I sold mine, I had 2 of the newer, black ones with the footswitch on them... Great way to get the Boston guitar sound without a Rockman device. I've never tried the blue one, but it's older, so I figure it has the same noise issue (correct me if I'm wrong though).
    Anyway, glad you got your amp back and working. :dude:

    Don't sweat the small stuff, no magic there, just play and enjoy!

    Oh, by the way, my opinion is this tech seems like a winner, I'd say he did well by you.
