I built the crack + speedball and was getting voltages far too low on terminals 1 and 2 (about 40 volts each). When testing terminal 3 I caused a spark (fairly sure it was shorting terminals 3 and 4) and now none of the led's light up. The tubes still glow a bit, though, which is odd.
No, I did not get the crack working before attempting the speedball. I accidentally ripped one of the leads of the 3k ohm resistors, so figured I'd just push on (regretting that decision now)
The 270 k ohm 1 W resistor seems to be fried, its giving me resistance readings well into the megaohms.
Any assistance would be very much appreciated, and perhaps a list of components I should replace (LEDs, 270 k ohm 1 W resistor and the 3 k ohm resistors for starters)
