Peavey Filter Caps
« on: November 10, 2018, 04:43:43 PM »


Hey folks,

Thanks for the help already received on this fine forum.

My latest question : I have an old Peavey 260 Standard that has a good bit of hum in the output so it seemed replacing the ancient filter caps would be a good start , (right ? ).
i am aware by search that the originals are no longer available, 5000 uf 55 volts and that some have used these higher values. Will they work ? Thanks.

May or may not be those caps.  Scope the supply, is it full of ripple?  Are the connections or solder to those caps good and solid?


5000uf is  non-standard value, 4700uf would be the current thing to use.   You want to use 6800uf instead?  go ahead, it is just a guitar amp, not lab gear.

55v is also non-standard, so 63v would be the thing to use.

But look at the low voltage supplies, are they ripple free?  Are the main voltages ripple free?  Are the DC voltages wher they ought to be - ie none on the speaker.

Thanks for the info  Enzo.

I'll go with what you suggested, I just saw the alternate value suggested in an old post. I'll give the other stuff a try as well.

Thanks !
