Re: transistor ID?
people what was the collector voltage on the Si? I use a 4.7k emitter 100k base to ground and a 220k with a 1meg pot base to +9 with a .0068uf cap. The pot is to adjust the Bias. I tend to like the sound with the Bias at 7.2 to 7.5 volts with the Si. If one does not want to use a pot use a 470k base to +9. Yes the Ge is different than the Si the Si seems to be very sensitive to bias setting, thats why most of my effects have Bias pots.  
I like the "sound"of Ge add the challenge of a good sounding Si Fuzz,overdrive. For people new here R.G. had a mosfet treble booster circuit posted here a few? years? ago. when the rangemaster was being "rediscovered" here.  
Ken what voltage is the radio VW used 6V until 66 If I recall.
