I can't quite see from your layout, but shouldn't these points all be grounded separately (Speaker/OT, FX jacks, Preamp cathodes) to ground lugs mounted so as to keep the amount of wire as short as possible? In most layouts the only one that's wired is that cathode ground, since the jacks usually take care of the other points. I'd mount lugs near the speaker jacks and FX loop jacks, and ground the jacks to those. Seems like a recipe for noise otherwise?Bruciep07 wrote:The ground side of both cathode resistors/caps are tied together, then tied to the speaker out negative which is tied to the OT negative and effects loop jack negatives, all of which are isolated from ground because of the cliff style jacks. Stupid mistake, I didn't ground any of thatDeric wrote:Get the cathode voltages.... V2 and V3 plates are very high. Double check the cathode grounds for both V2 and V3.Check all your voltages cathodes included and post them...... I'll fix that in the AM, swap out the cathode caps to be safe and report back... Think I could have harmed the OT by lifting the ground? Thanks...
