Title: Jcm800- 2203 or 2204 internal pics! (inside amp)
Post by: jcm800man on July 06, 2008, 04:02:26 AM
I thought it would be fun for people to upload pics of the inside of there jcm800 builds.
It would help new builder such as myself we could look at our wiring, what wires to twist together Ect... and compare to ones built by nik and other more pro.. more experienced builders on this forum.
it would help to list what mods you have done if your amp has mods and what model it is the 2203 or 2204.
A large/medium inside pic would help me and others heaps and would be fun experienced builders too, to compare theres with other experienced builders. Could be done in other sections of the forum with other amp types.

thanks

found his site, very helpfull his diagrahm of the jcm2204 was better drawn than nic's (sorry nic) easier to follow for novice. Only thing is he had changed a few thing like main board to what is supplied in nic's kit.
but still very helpfull am going to refer to this for my build.
Still think it would be cool to look at other people builds! not just for my purpose but everyone would get a kick showing off there amp!!!!!!!!!!

I built a JCM800 2204 (50 watt). All parts from Nik except transformers/choke.

Turned out to be a great sounding amp. (Wasn't surprised by that) ;)

I modded it some - Removed the treble peaking components and used a 68k grid resistor. Went to 100pf across the PI plates. 5.6k on V1a cathode.
