i immediately notice something missing. the orig varitone has a choke. it is common knowledge that the choke is where all the "tone suck" in a varitone comes from... (not really but yes) and as such they were freq snipped out of the circuit on many original 339s. (and just reading curtisa pointing this out too). not sure that even if you could find a matching original choke, you are likely going to find that it drops the output and makes the pickups sound 'weak'. just 2 cents.
The notion of the choke as a "tone suck" misunderstands its function. The choke works together with the variance inductance and capacitance values of the varitone to create notch filters. Each setting effectively eliminates a distinct frequency range from the output. If you want to keep all the frequencies in the output, just use setting 1 on the varitone which effectively bypasses the notch filter.
