Can anyone help with a schematic or (dare I hope) a manual for the TRC-109.. Coast Guard transmitter/receiver pre-WW2? Finally found one with the help of John N9HRT.

It's a simple little fella.. 6L6's, The receiver tunes 2 - 3.5, but there are original transmitter crystals for well into 75 Meters. 

However, it is densely packed and has some very involved power supply quirks, so I am not looking forward to tracing out the wiring. And even if I do, I'd have the task of moving the receiver into 75.

Any info would be very much appreciated.

Thanks.
