Dear community,
I am reviewing an old modification (very poorly executed…) that was done on the two tubes modules representing the final stage of my hybrid AMC CVT3030 amp.
I don’t have those modules anymore and I am thinking of applying the same mod to the present ones since it’s only about replacing four capacitors and one resistor.
I highlighted in the schematics the components that were changed and I am adding also some pictures.
Could you please take a look, possibly indicate if the changes make sense to you and which capacitors I should buy?
For instance, I could not find online the green Russian caps but I’m sure there are good alternatives.
C507: 10k100 white bulky cap, no idea what that is
C502: 3u3 400vdc +/- 3% Mundorf MCAP
R520: 12k
C505 / C506: K71-7 0,1 mk +/- 2% 250B8604 green Russian caps
Thanks a lot in advance
Fabrizio
