Hi guys, new here
i'm restoring a Rhodes "Peterson" i think with the 4 pins din connector.
So far the preamp and psu with original Germanium transistors is ok.
Small dc offset problem on the two amp boards (One with og germanium transistors and one replaced with "Asz15" transistors ages ago).
The one with og transistors has -1.1vdc of dc offset
The second one has -0.23vdc of offset
Any recommendation to fix this issue?
(i'm ok with electronics but not an amp pro)
Is it fixable by tweaking the 2.7ohm resistors?
or should we bite the bullet and do the silicon mod?
thank you!
