[R-390] test equipment question

[Steve Toth]

Some questions for the veteran radio techs - I'm organizing to start work on a couple of R-390A's I just acquired.  What test equipment do I need (as opposed to "would like to have") to get these babies running??
 
What I have now:
 
TV-7/U tube checker and spare tubes
AN/URM-25D signal Generator
Heathkit VTVM
Digital VOM
Digital Dial / Direct Freq Meter good to 50Mhz
 
Looking at the Y2K manual, pg. 1-12 and looking thru the stage-by-stage troubleshooting steps in Section 5, three other items are mentioned:
 
1.) RF Multimeter - can I use an adapter with the VTVM or VOM?  How?
2.) Audio Oscillator that covers 425-3500hz @ 100mv
3.) Oscilloscope that can cover .2 to 2vdc/cm
 
If I do need'em what inexpensive models should I look for at ham flea markets (got a big one coming up in the Northwest), places like Fair Radio, on Craigslist and (last preference)Epay?
 
Thanks.
