Good morning /afternoon to you. I just preformed a start up on the triwatt. I ended up using used tubes as I am waiting for some tubes I ordered to come it, and I have a couple questions, I have 12ax7's in v1-3, at7 in v4 and old RCA 6v6's from a garnet amp in for power.
My readings are
V1 1:132 3:1.3 4/5:3 6: 118 7: 0 8: 1.1 V2 1:199 3: 1.2 4/5:3 6: 126 7: 0 8: .7 V31:287 3:1.6 4/5:3 6: 190 7: 0 8: 1.6 V4 1:286 3: 76 4/5:3 6: 265 7: 38.8 8: 87.3 V5 and 6 2:3 3:471 4:437 5:-32 6:-32 7: 03 Now I suspect when my new tubes arrive, these will change a bit. Most seem within spec as I read it, But v4, 5/6 seem to be a bit out. Do I wait for the new tubes I should also say, I missed a couple jumpers on my initial start up, I did have a little heat from the Zener diode area. Once I have some time, I will be looking at it again. The jumpers I missed were between 620k and 180k next to the diode there, the one between the 2k2 and 7k5 near the bus bar
It does fire up, and I did plug a guitar in, very low noise floor, and the tone is beautiful. I am excited to get it finished once I have some more time to set aside for it.
