So I had the Crack assembled and working and began the speedball upgrade
I am new to DIY soldering and circuits and I failed to recognize that the 2N2222A and 2N2907A transistors were different despite the big red warnings in the manual. I thought it was referring to the resistors, not transistors.
Anyways, a quick run down of what I did:
[list type=decimal]
[*]one 2N2222A on the bottom right small PC board
[*]one 2N2907A on the large PC board
[*]finished assembly, powered on...Tubes lit up, powered off to test voltage
[*]powered on to test voltage, noticed not all LEDs were on... little bit of smoke... powered off
[*]removed PC boards from Crack, checked all solder points(re-did a few)... reassembled, powered on, same problem as before: tubes lit up, some LEDs on, and a little bit of smoke
[*]removed PC boards again, noticed the swapped transistors
[*]desoldered the wrong transistors from the small and large board, soldered them in the correct location
[*]reassembled, powered on... and here is where it gets weird
[*]
[*]I now can no longer get the Tubes or LEDs to power on
[/list]
I am going to go ahead and assume I fried the 2N2222As and possibly the 2N2907As, is there anything else I should check and/or be worried about?

- Tubes turned on
- LEDs on the smaller boards were all on
- LEDs on the large board were off
- LEDs and Tube light begin to slowly fade out until they are completely off
[*]I now can no longer get the Tubes or LEDs to power on
