Step 28 of the assembly instructions calls for plugging in the board and measuring the voltage output at the end of a diode. When I do this I'm seeing not 60 VDC, but closer to .6 VDC (I've checked the scale of my mulimeter several times). Up to this point everything has seemed to work correctly. Any help would be greatly appreciated!
You are good! I think that you are right - I completely misread the step 23 instructions (I won't elaborate on how I interpreted them - it seems pretty ridiculous in retrospect). I'll be unsoldering and resoldering later today - I'll let you know how things work out. Thanks!!
The high voltage transistor did not survive (at least it's not looking good) the surgery. Is it possible to order a new one? Is it a fairly standard part (available at the local radio shack), or would I be best off purchasing directly from adafruit (or, third option, specialty electronics supply house in/around SF, CA??)
going back a few posts - I purchased a new high voltage transistor from mouser, and all looks good so far!! Thanks so much for your help!! (it beeps when plugged in, and we are seeing the described voltage behavior in step 28.
