1965 Fender Reverb unit noise / hiss problem

[poligow]

Did you try this? (listen with reverb on, not bypassed)

no, i didn't had the time to try this yet, i'll keep the board informed

just tried to disconnect on leg on the 0,05 cap :


same problem /noises, even worse ... time to check for the resistors ?

i tried to replace the 2,2M and the 100K resistor, damed problem

Does that mean you did change those resistors?

Perhaps try partly removing the 7025 and then pushing it back in - to wipe the contacts of the valve and valve socket. Try removing the 7025 (if you haven't already). Try replacing the 100k and 0.1uF parts on the cathode follower stage. The aim is to clarify what and what isn't working as it should.

removing the 7025 and cleaning the socket was already done, as well as trying a new tube ... with no effect

i'm currently running the reverb with my Boss TU2 in front of it, so i can play without the noises, but i will try to replace the caps / resistors as suggested.
just need to order the parts ...

thanks once again for your help
