As mentioned above, it reduces highs, but it also stabilizes the sound and keeps it from getting too loose.

im i wrong or you wrote 39 instead of 36?

Ibeen working on some 39, last year a client brought his jmp 76 with the 39++ mod on it... im working on some schematics, its a very complete mod with 3 channels but its not the AFD sound, its de Lynch/Demartini/Aldrich sound.

If you what to try some real confirmed #39 spects take of the 2n2 cap on the #34, put a 680n on the second cathode insted of the 100n and a 680n on the CF
yes 39, i have the right scheme, & i have done a few small changes, thanks for the info

do you have the #39 schem?

Find the Caswell work not a good idea....isn't the right sound....34 emulate 36 so the stages voicing are the same

I actually like the Caswell sound on the two I have done, I agree not AFD as you hear it on the record but a useful tone nonetheless.

i told them benny but they wont listen to meee

when i tried the original #39 mod it was great but its not the afd sound, not even dialing in all the possible settings.

Soon i will stop talking and start posting some audio samples!

This is understood by the sample of Caswell ..... just use your ears

The 39 mod isn't really like the AFD tone, but it only takes you to change a couple of parts to get it into the ball park.

Ball park is funny but isn't afd tone.....

I've just been playing around with a 1k5/1u on the 4th stage which is sounding pretty nice. Now I just need to shape that tone some more.

try with 1k5/470n and 22n-470k/330k, frank told me this years ago and its been working for me
