It Works!

Last night (Thursday 19-Feb-2009) I finished connecting all of the remaining wires (so I thought). I plugged it in and nothing. No sound no lights. So I started tracing the wires and found that instead of the 6.3 volts of heater voltage to power the light. It was actually getting 600+ volts. Luckily I had ordered two bulbs. So I de-soldered the light wires from the high voltage tube socket pins, and put them on the heater pins where they should be, oh and also replaced that burned out bulb. I then flipped the power and the light glowed. The next step was to turn the standby on, but no sound. Hmmm. I then started to carefully measure voltage. I then quickly figured out that there was no voltage coming out of the rectifier tube. I looked at my plan and it looked right. I then looked at a different plan (some what similar to my version). Found it, the center tap for the High voltage wires needed to be grounded, not unhooked. Turned everything off, drained the caps and grounded the HT center tap. Plugged it back in, picked up the guitar and slowly turned up the volume. WOW! It worked. After a few minutes trying all of the inputs and such I can say that it sounds 10x better than I ever imagined it could. Though I might be a little biased.
Tonight I did a photo-op with it plugged in and the heaters on.
