When the 8955 Whiffy was floating at 13.7 I fitted an inline 500-ampere Schottky rectifier to drop voltage three tenths. When the Whiffy smoked and upon autopsy I damaged several ribs laughing, I now use the BORG. But it is going to be replaced by the GigaWatt.
The 10-amp Whiffy fuse failed. I replaced it. Plugged it in. One of the two bi-polar transistors popped off a chunk the side of two dimes, stacked. The shrapnel pinged off my safety goggles. When I unfastened the heat sink from the corpse I found Whiffy did not use a micro-gram of heat sink compound on the cheap grade Chinese heatsink "counterfeit Berquist Sil Pad" pad. Wiffco may be manufactured in northwest Pakistan or the Hindukush as far as engineering land mines are concerned.
