jjmt,
I have been posting a recent recapping and general cleanup job on my Ampeg GuitarAmp. The amp is very close to the amp you have in its lineage. I have a serial number that puts it at a May 1956 manufacturing date. I have posted my recent changes and some pics in the "workshop" section of this forum. Until very recently, this "50's Ampeg amplifiers" forum was overwhelmed with spamm, but that seems to be resolved.
I used the 835 schematics to help diagnose and repair my amp as well. I have drawn up some sections of my amp while replacing components.
I acquired this amp so many years ago that I cannot recall where....but I think it was a yard sale item and I got it for cheap. When I turned it on, it hummed so badly that I turned it off and put it aside for 25-30 years. I had a Gemini VI that I used part of that time. I decided a couple of months ago to see if I can fix the GuitarAmp so I could stop lugging my Gemini to/from a buddy's house.
I love the sound of this amp, especially the tremolo. I opened up my Gemini last week to replace some caps in that, and while I had it opened, I replaced the tremolo speed pot in the Gemini from 500k to 1M to extend the range of speeds on the tremolo down to close to what the older GuitarAmp has.
So check out my posts at http://www.vintageampeg.com/forum/Thread...aramp-1956
(I have yet to figure out how to post active links.)
