I have always wanted this traced if anyone at all has one.

"Quality" DBA solder job, as usual.

Thanks in advance.

It's two Orman Mini-boosts in series. They don't need matched fets.

Hello from years ago. I just measured the transformers in a newer-ish Pignose (pcb date is from 2014) and they are as follows: Driver Transformer: Primary 60ohm Primary CT 30hm Secondary 45ohm Output Transformer: Primary 8ohm Primary CT 4ohm Secondary 1.3ohm Secondary CT .3ohm Photos: https://imgur....

Yes.

So the Klon's 3 JFETs need testing. I've found the pinout online but am unclear on testing.

edit: also 2 of the diodes are reading about .35 in both directions. That does not sound good, although I tested with them wired into an unpowered board.

Soldered the wires directly to the switch lugs, bypassing the pcb. Same problem. No signal output when switched off and there is a loud hum. Switched on signal is passed but is thin and a bit raspy and noisy. Off to take values.

Thank you!!

Thank you. Yea, I bought lead-free, non-pre-tinned, non-pre-bonded wire. I have a bunch of switches and switch pcbs coming from 3pdt so hopefully the ol' Klon isn't dead. Thanks again! edit: The rest of the board is pretty clean, in my opinion. The two clipping diodes in the photo look a little cold...

Hi, This is my first project ever and, of course, I managed to mess it up. I expected this. I also expect that I will need a new switch and switch pcb, unfortunately: https://i.imgur.com/DPerGPOl.jpeg In order to continue troubleshooting I'm assuming I need to collect the values for the components b...
