I have a pair of working solid state replacements for the 866/A and 3B28
rectifiers. Rated, 10,000 volts at 3/4 amp. 5" high, 4-pin, ready to plug
in. I have seen these go for $65.00/each, but will sell both for $25.00 plus
shipping. These are almost a must have for the Collins 30S-1. Take the load
of that tranny, install these.
