Hi All !

Don't have much experience with theremins as such, but since the non 
working ones seem to be built into scratch-built cases, read on :

On a visit to a friend he had installed a Big Briar Theremax on a mic 
stand, and was fooling around with it .  The top of the case was off, 
and we were joking at how it would not go down in pitch very well, 
when i touched the wire going from the base of the pitch antenna to 
the circuit board .  The bit of bottom of case this wire runs over 
has a foil groundplane .  When pushing the wire more over, and closer 
to this foil, the pitch dropped several octaves, the lows going 
distinctly toc, toc, toc ;-)  Some capacitance at play here ?  Dunno, 
but now this thing seems usable at last .  And this was with the full 
kit .

Food for thought ?

Hope this helps .


Keep 'em oscillating :)
