I purchased this set from another collector in August, 2009. My set included a DY-44 dynamotor, which allows the set to be powered fomr a 24VDC source. I’ve traded the J-72/GR terminal box (shown below) for a CH-291 battery box (not yet shown here). Rather than using original BB-54 wet cells, I installed six 6V gel cells (in parallel) in the box.
The set can use either an antenna whip which attaches to a swivel mount on the back of the transceiver, or a remote whip antenna. I have the J-72/GR matching unit which allows this radio to be used with an AB-15 antenna mast base, but I hope to get my hands on the correct built-in whip.
The SCR-619 set could be vehicle-mounted or carried on a special pack frame. In vehicular installations, the set would include Battery Charger PE-219, two each Battery Box CH-291, Mounting FT-506, and Terminal Box J-72/GR.
I hope to obtain the necessary accessories for a comple portable set. I’m missing the whip antenna used for man-portable use, but I can still use the set at a fixed location with standard AB-22/23/24 whip elements which screw into the mount on the rear of the transceiver. I’m also missing the rare FT-505 pack frame mount. I was able to borrow one of the few known ones for a while to photograph it, and I created a solid model of it in case I ever find the gumption to have replicas manufactured.
Here is the BC-1335 schematic diagram from my April, 1945 printing of TM 11-879, scanned at 600 DPI, with and without some added annotations:
