Hi Jeremy
Well done on successfully completing it.
I find the analogue switches the hardest to solder. There is not much on them to hold while aligning and soldering them. It can be difficult to see the pin 1 mark and if some flux gets on top of the case nearly impossible to see it.
I had one modulator with the same problem as yours. The rest of the pack of 10 that it came in were OK.
My method of fault finding was a bit crude. I left it powered up current limited at 1A for a short while.
A finger to the case of the modulators revealed which one was faulty.
Happy viewing with your Hedghog
