[Milsurplus] AN/PRC-47 and AN/PRC-74 questions

While I have neither set at present, I've been thinking about both of
them and have some questions about them.

On the AN/PRC-47 - What is the current drain when transmitting on low
power?  Also, someone told me what transistors will work in the 24
volt inverter but I've lost the reference.  If I could have that
again, I'd greatly appreciate it.

On the AN/PRC-74 - Again, I had a reference for transistors that work
in the PA, albeit only producing some 5 watts output, which I can't
find.  If I could have that again, I'd appreciate it.  And finally, is
there any possibility of modifying the output network so it's happier
with a 50 ohm rather than 70 (75?) ohm load?

While there is a PRC-47 in my future, I'm also hoping to find a just
plain PRC-74 with a blown PA to pervert with USB/LSB capability,
variable tuning, and hopefully a modified output network.  Both would
be for use here with the emergency services on 80 & 40m LSB and 60m
USB.

Best regards,
