[MRCA] 10-meter FM Progress

[Al Klase]

Gang,

I took a chance on a disreputable looking PRC-9A on E-bay.  It arrive 
promptly, and is now functioning reasonable well in the shop, surrounded 
by four separate bench supplies, and a rat's nest of wire.

I want to get this running for the MRCA meets, maybe even the Spring 
Meet in Sussex County, NJ, 16-17 APR.  So I'm looking to buy some stuff.

1) A battery box.  Would consider a PRC-8/9/10 parts set.
2) An AM-598/U amplifier/PS.  This might obviate #1.

Does anyone have any experience powering one of these radios?  I found 
Dennis Stark's writeup <http://www.qsl.net/wb4tur/images/dcdc.htm>.  But 
that's probably not the way I'd do it if I build a DC/DC supply from 
scratch.  These things need 1.5 and 6 volts at about a half amp each, 
and 67.5 at about 20 ma. plus 135 at 40 ma on transmit.  I don't thonk 
dollar store 9-volters are going to do the trick for long.  Silly little 
thing has about 15 tubes.

Also, does anyone have a scan of an accurate schematic for the PRC-9A.  
It's subtly different from the original set.

Any help appreciated,
Al
