18W Power Train Serial 002

cdn$ pricing.  New Power Train.  Based on F****** P*** Taco.  Serial #002. I went over that circuit with a fine tooth comb.  Got to the heart of it and added a couple things.  Power Train has a tube, not solid state loop, has presence and depth, a wattage control, and a standby switch.  email me direct phaezamp@gmail.com (messaging through the site is a little flaky)
