Peavey 6505 plus schematic

Post by Stevem »

Anyone got a preamp schematic for one of these pups?
The one I have has hiss like it's going out of style emanating from V1 and I have swapped out both plate load resistors with no improvement, and yes it's not the tube!
Thanks in advance !
When I die, I want to go like my Grandfather did, peacefully in his sleep.

If I remember correctly Peavey 5150 II schematic is exactly the same as 6505 plus

Thanks for your time and input , but the 6505 has 6 preamp tubes and the 5150 has only 5 .

If you call the tech service or repair department you can probably have that schematic within the hour. Peavey folks are friendly and very accommodating.

6505 is the 5150,6505+ is the 5150 II,simple as that,schematic is around the net.
They had just changed the name because of EVH trademark.
The combo is different though.

Please correct me, if anyone solved the hissing problem with the 6505's. But I guess it's quite normal, lots of tube stages. -_-

Using the schematic linked in post #2 above, if it has that 68K (R22) on V1A, install a short.

What helped out in that one I was working on was changing out that 68k for a good quality 1% 2 watt metal film.
