Need some help! TL;DR goto end....
My elderly next door neighbour collared me the other day and asked me if I still played guitar. I told her that I did, but not much due to family and work stuff. Anyway, she proceeded to tell me about how her son had met a woman last year and gone to Estonia or something, he was playing in a band over there but had left a lot of amps in her garage (he's a bit of a musician, rocker, uni student type).
She said she couldn't put her car in her garage and would like to with the weather and all. She said her son didn't want to/couldn't deal with the amps, didn't know if/when he would be back and to get rid of them/sell them if she wanted. She had taken a couple to the dump(!), but couldn't lift them and she only has a small car, also she didn't want to deal with ebay, newspaper ads etc.
Anyway, she asked me if I wanted them... Well as a musician/hoarder/geek I couldn't say no and I knew I'd be helping her out. So, I pulled up my car and opened the boot, expecting a couple of old practice amps or similar. She looked at me shaking her head and said 'maybe you'd better see them first' and when she opened the garage door I was lost for words...
All down one whole side of the garage was amps, speaker cabinets and head units, but there's the problem... It was wet, cold and damp in there (with some beastly spiders!) they had been in there a long time and that is no good for delicate electronics!
One in particular caught my eye, it's a Carlsboro GLX-85 Special Edition (actually not that special by all accounts and not worth a great deal) so I thought I'd take that in to the house clean it up, dry it out and give it a blast! I thought I could even donate it to the school if it was any good. Unfortunately I was disappointed, it sounded horrible the controls were scratchy, I couldn't turn off the distorted sound and had loads of drop-outs, it sounded like the sound was struggling to come out then blasted at full volume...
However, I have taken it apart like a good geek and found nothing really amiss, apart from two components marked W22 R33 5% on the rear circuit board and they looked corroded. I have attached pictures, but I don't know what they are, where to get them from and how easy they are to replace. I looked a little on the net, but didn't find anything that looked the same. I don't have any circuit board/component level soldering experience, but I don't think the amp is worth the money to have it professionally repaired... Also, if I do change these it might not solve the problem, but if I try I might make it worse or destroy it completely! HELP!
Check for bulging/leaking caps also.
That component is a 0.33 ohm resistor and is unlikely to be the cause of your audio problems. Try to clean / replace the potentiometers and as others have said, check for bulging capacitors.
