[Milsurplus] Transistors for the PRC-47 Power Supply.

Hi All,

There were some questions a while ago on transistor replacements for the
PRC-47 supply, with 2N-1544, 2N-2287, and 2N-1653 being mentioned.  I
noticed while looking at my schematic for the Collins test fixture for the
power supply that they use 2N-2833 transistors in it.  Don't have my
transistor books over here, but I would suspect that these would also work
in the radio.  Any one care to look them up?  Are they silicon or Germanium?
power rating, etc.  If silicon, the schematic is there to convert easily for
the proper bias, etc.

Cheers,
