I was wondering if anybody has any advice for tuning/calibrating the coils the first time on a Theremax, beyond what is stated in the instruction manual.
I had this same problem with a previous Theremax I ordered off of eBay (it came, fully assembled, in the lectern case, for $125 but... didn't do anything. I used the gator-clip jumper to bypass the volume circuit and discovered the pitch worked like a charm. But with no jumper... I could not, for the life of me, tweak the volume coils to get any sound out of it)
I figured, since I didn't assemble that one and had no idea what had been done to it or how old it was, that maybe the coils were broken or something ; since I wanted to build mine into an Atari 2600 case anyway, I sold the lectern one on eBay and ordered mine.
Well, not it is all assembled and... once again, with the jumper in place I was able to get the pitch working (although it's a bit of a pain because my case design makes tuning even more difficult than usual -- I'll post pics later)
BUT when I remove the jumper and follow the directions for turning the coils, I can't get a single peep out of it.
Any ideas??
I find it bizarre that the same thing happened with a pre-built one as with a brand-new built one that I know should be fine. I must be doing something wrong...
