 OK, time for me to try to get some of these old guys working 
 again... Below is a list of what I've got thats broken. If anyone has 
 any experience or repair tips they can offer for any of these I 
 would greatly appreciate it.
 
 Arp Omni - No audio from synth section
 
 Arp Odyssey mk3 - VCO2 out
 
 Roland Promars - VCO2 out, odd front panel behavior
 
 Prophet-5 Rev. 1 - Gee, a NW Rev. 1?? :-) Various LEDs flicker 
 and fade out on power up, no audio or controls working. Tested 
 voltages at power supply and voltages were off quite a bit and 0V 
 on -5 and -15 so replaced w/new regulators and tantalum caps 
 and -5 now OK but -15V outputting -20V, WTF? Also unreg 
 measures about 28V instead of 22V.
 
 Rhodes Chroma - All EPROMs were corroded - replaced w/new 
 ones but still powers up in weird state, no audio or controls 
 working
 
 Roland SH-101 - Sequencer/LFO does not function
 
 Roland SH-101 - Won't power up from batts or AC
 
 Chroma Polaris - 1 voice out
 
 Oberheim SEM - no power
 
 Oberheim SEM - VCO2 constant high freq sound
 
 Sequential MultiTrak - Sound is totally muffled as if VCF is stuck 
 w/low cutoff freq
 
 Moog Prodigy - no power
 
 Moog Opus-3 - Always has slow attack regardless of EG setting
 
 Whew! Got my work cut out for me for sure. I am most interested 
 in getting the Chroma and P-5 working first. Thanks for any help 
 or suggestions!
