Not sure if this is the right place to post this, feel free to move it if its not.

My Akai am-a201 keeps blowing internal fuses, I switched speakers around again today and the amp was very quiet then suddenly very loud, and then the left channel went dead, sure enough left channel fuse gone.

Had a good look around inside with a decent torch and found this...

I know nothing about electronics.....but thats not good right? :)

Would it be worth me having a crack at replacing them or should i give up on it, my soldering is not the best ( actually scub that, its rubbish )

Be a shame to bin it if its only this that need fixing?

Be greatfull for any ideas, thanks guys.

Keep yours for spares :)

Thanks for the reply, nice to see another one, but having looked at other things on the amp like the spongy switches ( broken 80s plastics ) and spring clips instead of binding posts. I dont think I would spend £40 on one, not when there are so many other amps on ebay for around that money.

I may see how much it will be to get replacement...umm resistors? its only 4 wiresto try to solder i suppose if its going to be a few pounds ill have a crack at fixing it i guess, i was given it so it owes me nothing ( Well £1.50 for fuses. )

I would say there's something more going on that just the blown resistors - something further down the line caused them to blow and if you did replace they might just blow again.

The wire links just above look corroded and messy too - possibly gunk leaking from the big black capacitor which also looks cracked near to the bottom. I reckon your problems aren't finished there.

I hadnt even considered it was somthing leaking, i thought it was some kind of glue, but you could well be right.
I think this one is heading for the scrap, unless anyone on here wants it for canibalising that is.

What was the outcome of this? Theres nothing wrong with the cap in the picture. That is glue at the bottom, and you can see it at the bottom of some of the other caps too. If the electrolytic had failed the flat top would become 'puffed up', a sort of dome shape.

Hi Tommy, I scrapped it i'm afraid, as much as I hate doing that :(
I found the parts list and diagrams, looked at the parts, the "burnt out" parts were designed to go in case there was a problem somewhere else, by the time I had added up the cost of replacements, plus postage, plus the other problems the switches had... and not knowing if doing the work would solve the problem V a fully working Cambridge audio A1 on ebay for 30 quid with the postage.. it didn't make sense.

However if i see another one really cheap, i'm gonna grab it. I really liked the sound, I think one running perfectly may have the edge over the Cambridge.
