Correct schematics for S.I.R amplifiers #34 and #36

[Antônio S]

Hello guys.

I'm looking for legit (or close) schematics for the famous S.I.R amplifiers #36 and #34, made by Frank Levi.

A friend found this schematic in his personal files (attached). What do you think of him? We will be happy to receive different opinions.

We would also like to hear from other schematics so that this becomes a rich discussion of these highly acclaimed mods.

Thank you very much!

Unless someone rented the amps and opened them up to draw a schematic, there’s no way to know what the mods are. There’s a lot of speculation.

I agree. Some people claim to have the right schematics or at least have a schematic that sets the tone for the AFD.
