Hi there, I tried to bump an old thread earlier today but now I'll try to ask a more detailed question. So, I just finished my Electrovibe and I've double checked every solder joint so far. I have bypass signal.
The issue is, the lamp isn't pulsing. It's static. The two trimmers work just fine as brightness change when I tweak them. I triple checked all solder joints and all the trannies (I got them on sockets). I tried again and suddenly the lamp was pulsing as it's supposed to. So I closed the enclosure to give the pedal a try...but no effect came out...I reopened the enclosure and again, the lamp wasn't pulsing anymore.
I noticed that Q3 is getting a bit hot and the lamp is flickering when I move the PCB around.
Any idea what/where the issue could be? Normally when a tranny heats up it's because of too high current at the collector, right? (or am I wrong?)
Thanks for any advice!
EDIT: I got the lamp working. But there's only sound (still no effect) when the switch is on the vibrato position...when I switch to chorus it's dead quiet...still, the only two components on the PCB getting hot are Q3 and the voltage regulator (L78L12)
