WH2O problem 3784 !! Soundcard burnt

[newdos]

Hi Guys, see pic of my WH2O soundcard here(actually swapped from FT) you can see substantial burning around these components yet the board is still working. Is this a common issue? Do I need to replace these and if so which ones and do the values (wattage etc) need up rating ?

Also can see in the pic the caps look a bit puffy as well

Cheers Kev

If the caps are bulging they need replacing might be worth sending the board off to andy or Luke if it's that bad

Probably been running on full volume for years. Dead easy repair.

ok so which components should I replace

I'd replace the burnt resistors and clean the board whilst they were out. Change caps if they're puffy.

Never seen a sound board that bad. And you say it's out of your Fish Tales??

 

[newdos]

Yeah daz sounds is fine as well !!

That's what happens when you turn it up to 11

Also those corroded fuses look like a future intermittent power issue waiting to happen, so you'll want to replace those and clean up the fuse holders as well

C28 will have been the root cause there. That's a 1uf tantalum capacitor. They like to short circuit and explode from time to time. It'll still work (like you say it does) but you'll have a noisy power supply now.

So the heat has also destroyed R11, which is on the pre-amp side of audio channel 2. I'd be suprised if the sound has not been affected by that, unless the resistor is still functioning

Yeah I have new cappy and resistors ready fit - see how it goes after that!!!
