I've assembled my Crack (without Speedball) and the initial check of my resistances were all good. When doing voltage checks on the input tube (around A2 or A3), I heard a snap, after which I immediately shut down the amp. I did a visual inspection and all looked ok, so I restarted it and got normal voltages except for the following:
1 - 117vdc
7 - 126vdc
A6 - 118vdc
B1 - 148vdc
B3 - 147vdc
the LED from A8 center pin did not light (I don't know if it ever lit), but the one from A3 to center pin did. I confirmed orientation on both LEDs. The 3K resistors got really hot while doing the checks. After I powered off and pulled the tubes, I re-ran the resistance checks and now got the following abnormal readings:
1 - open
2 - open
4 - open
5 - open
13 - open
everything else was normal. I was thinking that the LED from center to A8 was bad, but with all the opens now on resistance checks, I'm not sure. Any help would be appreciated.
TIA
