For Sale Military RTTY monitor scope model OS-11/FCG-5. It was made by Waterman (of "Pocketscope" fame) for Teletype Corporation. It is a gray, 19 inch rackmount using about 5 inches of rack space. The CRT is a 3RP1 and the rest of the tubes are 12AU7, 12AX7 and 12AT7 types with the sole exception of the 2X2 HV rectifier. The unit looks very good or excellent and it all original including the bottom cover. I was able to get it to give a trace which looked normal. But I did not test it any further than that. It has vertical and horizontal amplifiers and a sweep circuit. The sweep seems to be working. Below the amplifiers are pin-jacks for inputting vertical and horizontal signals. I did not try these inputs and I am guessing that the amplifiers only do anything when these inputs are used. The only other connector is an SO-239 coax connector on the left rear chassis top next to the Teletype logo plate. I didn't try anything in that connector either. So it may not be perfect but it doesn't smoke and does have a trace. As-is. $109 OBO
