Hi everyone. I have a Fender M-80 which came in making a lot of noise as well as loud switch on/off pop noise. On opening it, I found two zener diodes and  filter caps O/C. Replaced these, and the noise has gone but the pops remain. I have tried turning the volume down but this has no effect. I would like to put a mains filter cap across the switch, however, this is a DPDT switch with active and neutral on one pair and two connections running to a thermal breaker on the other pair. I checked the breaker and its in working order. Can I still use a filter cap and will it be effective?
Thanks,

Hi all. Customer brought in an old Dynamic solid state which looks like its had one mod too many. Don't want to give up on it, so wondering if I can lay hands on a solid state amp kit? Ideas? Cheers
Rhea.

Hey all. Doing up a little Fender Harvard Reverb Solid State Amp. The input jacks were rusty, so decided to replace them. So I rewired them, like the original (or so I thought) and input 1 is silent and input 2 buzzes quite loudly.
I have wired as follows:
Input 1 Lug 1 +ve (red wire)
Lug 2 Ground (Shield) also to Lug 3.
Lug 3 to Lug 3 input 2
Lug 2 to Lug 1 input 1
Lug 1 Black wire.

I am certain in copying the original I have gone awfully wrong.
Appreciate ideas and help.
Cheers

G'day all. I come from the South Coast of NSW. I repair all things electronically musical - guitar amps, pedals, sound desks, stereos and so on. So I have a Woodstock in the shop with no sound. Tests reveal the output MOSFET to speakers is kaput.
I haven't got any circuit diagrams or tech info to work off, so working without a net here...
What I am looking for is the specs for this 5 pin output MOSFET - yeah, no markings on the bad boy!
Really flying without instruments!
Any ideas?
Thanks
