[GreenKeys] Monster RTTY receiver- Looking for schematics for Russian P-155/R-155 receiver

[Bruce Gentry]

I am trying to find THE BIG ONE as far as Russian receivers go- an 
R-155, the nixie display monster that weighs a ton and has built-in RTTY 
demodulators.  There are plenty photos and descriptions on the internet, 
but so far, no sources of schematics or manuals. I will be glad to pay 
for manuals or schematic copies. When I decide to persue something, the 
first step for me is to get at least the schematics so I can decide if 
it is really interesting enough to spend the money on, and be sure I can 
work on it if I do.
