lovekraft Posted April 12, 2005 Report Share Posted April 12, 2005 Sorry, I can't find a schematic for it, so I can't help you! Quote Link to comment Share on other sites More sharing options...
ROBERTLATHAM1 Posted April 13, 2005 Author Report Share Posted April 13, 2005 (edited) lovekraft yeah it from what i understand is a late 50's to early 60's production date. it is totaly hand wired no board cicuits at all everything is original except for a monster cap on the ac line in. the tubes are 6-12ax7 RCA'S and 2- 6l6gc SYLVANIA'S. the RCA's appear to be original includeing metal shrouds over the tube. the sylvainia however look like new tube's. at any rate i use my marshall 8100 head on the tube chanel of course to pre amp into this head, as there is no gain control , only volume and tone. when doing this i was shocked at the tone and vibe of this head. i have always love jcm 800's tone, but this combo package(marshall 8100 pre-amp if you will harmony 535 head) gives me that tone plus the ability to produce some of thickest clean tones i have ever heard. if you could give me some insight on where i might find some tech data on harmony, silvertone or truetone amps as these where all basicaly manufactured alike it would help me tramendously. thank you robert latham Edited April 13, 2005 by ROBERTLATHAM1 Quote Link to comment Share on other sites More sharing options...
lovekraft Posted April 14, 2005 Report Share Posted April 14, 2005 Well, here's the usual suspects: http://www.justradios.com http://www.schematicconnection.com http://www.candisc.com/ranger/ Any of 'em might have a schematic for sale, and they're generally fairly reasonable. If the amp is as old as you think, it's probably due to have all the electrolytic caps in it replaced. Quote Link to comment Share on other sites More sharing options...
