[Boatanchors] Re: 160 Meter AM Question - Transverter

[kd4e]

OK, everyone take a deep breath and don't get too
angry but the HamGyver in me says "consult the
junkbox".

I happen to have a matched set of good 2SC2879 power
transistors in the junkbox.  Would they serve well
as a replacement for the dual 6146's in the '77
transverter?
