Birth Of The Gigawatt

[MEXICOWANDERER]

Jim in Denver's Megawatt has been perverted. Larger toroid choke, 80 amp 150 volt diodes rather than 30 amp 100 volt. Panasonic 680uf caps, 10x more airflow via two external roof fans. And...

57.2 amperes* into 12.0 volts for 9 hours and 10 more or less minutes. 16.67 wide open volts. Didn't even breathe hard. Cool to touch on rectifiers and bi-polar transistors. Like having a Derringer 12-gauge.

I did delta the three positive and three negative circuit board terminal strip output screws. Total fans drive current .84 amps. Transistor life will be a "maybe".

Your transistor issue might be on again - off again but overall it looks like everything has been rectified 🙂 Sorry-couldn't help myself.
