I Damaged my Amp?

[Bloke669]

I've tracked it back to a 1.2K resistor and a 470uF 25 volt cap.
Will need to do some more dismantling to prove the fault.
I appreciate all the help from you guys...I know I haven't been much help!
Cheers

I've tracked it back to a 1.2K resistor and a 470uF 25 volt cap.

To test if the caps have just shorted, you can simply remove them leaving in the resistors -- the amp will run fine w/o the caps for testing.

The caps are mounted very close to the pc bd so i'll have to dismantle the board to desolder them from the underside.
There is a wire from the pre amp bypass switch soldered on the same track at each cap.....so these caps would have taken some of the jolt when the interconnect touched live power.

Hi Guys
Just wanting to say thanks for the help I got finding the fault in my amp.
I replaced the two caps and eliminated selector switch and extra inputs,installed teflon insulated shielded cable between the input RCA's and the volume pot and the amp sounds Sooooooo SWEET!
.......and I have learned a lot to boot!!

warranty

You know, if you bought from the guy in canada there's a 1-year full warranty, plus 3 years labor warranty...

of course, if you bought directly from China you're SOL.


Am I the only one that finds it odd that the .6v switched input still passes through the volume pot? I'm using a phono preamp with its own volume control in that .6v input .... debating bypassing the volume control circuit too...

ChopperCharley.... Warranty??? The amp was fine till it was shocked... I don't think any company would cover abuse. So I'd say you did a great job repairing your amp and learned a bit?? This forum is excellent!!!

Charley is a girl's name. Charles, thank you very much.

And... the Canadian distributor doesn't need to know *how* it got fried.
