I just got four of these myself from small bear a few weeks back. I then tested that IC in a known working 9v bi-polar PS.and it was providing erroneous voltages.so.I burned out two of them this way before I figured that out. Pedals that use vacuum tubes at high voltage to give you true tube OD distortion, not gimmicky use of tubes at low voltage just to meet marketing needs. I later found that if I increased the amperage from my bench PS, the tube heaters would glow.and I measured the amps during this process.ended up somewhere around 200 - 350mm for the heaters.too much for the 1054.but I wonder if the 7660 would work? At this point the 1054 IC in the PS got so hot it burned my fingers. The moment I put the tube in, the LED went away. This is the real deal signed by BK Butler with all paperwork and original box with original packaging.

This is a barely used BK Butler Tube Driver in mint condition. what I found initially is that if my tube was not plugged in, my led on the PS lit but I got no sound. OKKO Diablo Boutique Overdrive G BK Butler Tube Driver with Bias Knob- 2014 2014 model. In fact, I probably should have just gone ahead and kept the Blue Tube, all said and done. I would have no problem getting either one again. Keys, guitars, bass, theyre pretty neat little boxes. Both, though, are very versatile OD/preamps. I don't have any 7660s but I plan on building a bipolar power supply based on what's on the schematic to rule the PS out. The Blue Tube seemed a little warmer and darker than the Tube Driver.
