Addition to list of Rangemaster transistors Put together an Austin Trebleblaster last night. I used a 2SB172 transistor with an hfe of about 120, and it worked great. Instant Beano, with a nice soft compression when you get above the 10th fret or so. Ended up using 33k for the base-to-ground resistor, and 2.7k for the emitter-to-ground resistor, yielding -6.7 volts as the collector-to-ground voltage. Everything else was as outlined in RG's doc (thanks guy, VERY clear and easy to follow).     A ne'er-do-well electronic parts retailer in my region went belly up and sold a stack of bubble packed 6-packs of NOS Japanese Ge transistors to another place, which are now going for a buck a pop. I have a very wide assortment of these (they come in "variety packs"), and hope to try and identify a bunch of other contenders for this simple but satisfying little gadget.
