Members BradG Posted November 16, 2007 Members Share Posted November 16, 2007 Does anyone know the preamp tube layout for the EVH 5150 III? Has anyone tried anything other than the stock JJ pre's? Thanks! Link to comment Share on other sites More sharing options...
Members Romanian Reaper Posted November 16, 2007 Members Share Posted November 16, 2007 Front row (looking at the front of the amp from left to right)V1 - Input tube for all 3 channels. V1A is for Ch 3, V1B for channels 1 & 2.V2, V3 - preamp stages for channels 1 & 2 (channels are switched via relays)V4, V5, V6 preamp stages for channel 3. V4 sets the high gain. Back row (looking at the front of the amp from right to left)V7 - loop, V7A send a & V7B returnV8 - Phase inverterV9-V12 - output stages. BTW, I'v used a ton of other preamp tubes with mine. Currently I have a Tung-Sol in V1, JJs in V2 & V3 and Chinese in the rest. Link to comment Share on other sites More sharing options...
