treble middle bass 18w

Not my first 18W build, but first TMB. This was built from a box of parts sent to me for assembly and test. It's identical to the TMB over at 18watt.com with two exceptions. The bass pot has a better range changed to 250K linear and I ran a shielded line from the volume pot to the tube socket, bypassing the 470K resistor on board, to keep it from squealing.
