RCA MI-31477 Exciter, Looking for docs
 

HI:

I picked up an all vacuum tube RCA FM exciter from eBay that looks to be for the public service bands. It is an RCA MI 31477, four RU tall, rack mountable. It should have included a TVM-129 crystal oven and it must be used with a few other chassis for power, Ic metering and power amp. I was wondering if any one has any connections to wherever I might be able to get a schematic and some specs. Photo attached. Feel free to contact me at karlwhansen@yahoo.com
