JMP Reissue w/JCM800 & AFD mods

Post by Aaron »

Just finished modding this Marshall head.
Clean channel has both the High Treble & Normal volume controls jumpered.
I've built a JCM800 style amp before, but this is my first for the AFD Boost.

Might have to build one from scratch now.

Is there a schematic for the AFD mod?

Thanks, with that clue and some Googling I see there are several schematics around!

Martin,

I think that whole 30 series of mods was on the Metro site.
I have them stuck away on a hard drive somewhere if you can't find them.
34, 35, - 39 maybe...\

Please understand that IMO an answer to this question is of no practical relevance at all. - Max

Hi Bob,
Interesting, I didn't know there was that many. Were they all modded by Caswell?
Back to the Google Machine.

I had saved some of the "SDM" layouts from the Metro site, but not all. Seems they have been archived here: http://forum.metropoulos.net/viewtopic.php?t=45057
