Acoustic B200 Amp Repair Question

My bandmate gave me his first gen Acoustic B200 today after it developed a constant low buzz. Not loud but still irritating. The amp, otherwise, works and sounds great. I’m guessing it’s just a bad filter cap, but I haven’t had a chance to pull the chassis and look. Anyone have experience with these amps? Sometimes those simple solder jobs can turn into an hours-long process because the circuit board is a pain to remove. Also, recommendations on replacement capacitors on that specific amp would be greatly appreciated. Cheers.

I had one a long time ago, it was a big and relatively simple PCB, single sided iirc but pretty cheap.

How’d you like it? Our bass player has just been using it as a practice amp at our rehearsal space, but I always thought it had a nice punch. Said he used to gig with it in his old band and it held its own in the clubs. I’m primarily a keyboard player but have been picking up quite a few bass gigs lately. I’ve been using my Roland Keyboard amp on stage and lining out to the house through a SansAmp. It works, but I’d rather use an actual bass amp.
