I'm trying to copy an old transistor theremin...but the transistors are old and the part numbers dont seem to be available anymore.
does anyone know or type of transisters I should use? The ones in the old theremin i want to copy say GA3437 on them. I searched on the web for Texas instruments GA3437 and got no results.

Any help would be great.

Thanks in advance

Hey Dean, i've run across a picture of "Sonic Wave" theremin that uses GA3437. Did you find out about them?
