![]() Two I fried, the other two I tested and they work.so I'm guessing what you got from small bear was good. ![]() A page about Gilmours Tube Drivers can be found here HERE DAVID GILMOUR TONES - David Gilmour has been an avid Tube Driver user since the 1990s. David Gilmours 1994 Pink Floyd pedal board with two 1986-87 BKB/Chandler Tube Drivers labeled 1 and 2. I just got four of these myself from small bear a few weeks back. I have a page about Gilmours various Tube Drivers and settings HERE. 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. 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. Heres when things get funky: Butler left Dean Markley in 1987 and started his own company, Tube Works, to build and market the pedal under the Real. what I found initially is that if my tube was not plugged in, my led on the PS lit but I got no sound. 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. It sounds pretty good, and really shines when stacked with another overdrive - but I think it would be better with. ![]()
