TUBES - Lot of 4 JAN 813 Transmitting Vacuum Tub: Lot of four vintage 813 transmitting vacuum tubes from storage. Includes military JAN tubes from RCA and Westinghouse. These were used in ham radio transmitters and RF amplifiers.
All tubes are intact with no cracks and the getters appear good. Filaments were checked with a meter and all show continuity.
Tubes have been stored for many years and are sold as untested beyond filament check.
Great for ham radio transmitter projects, restorations, or collectors.
813 tubes were commonly used in high-power RF transmitters and are getting harder to find.

ANTHF - HF Yagi beam or quad wanted in N FL area: Looking for a 10-20m tribander or cubical quad antenna for my Rohn 25G tower. Also need a mounting shelf to fit a rotator like Ham M inside the mast. ( This shelf is smaller than the shelf designed to fit over the top end of a 10 foot section and is held by U-bolts. )
Can dismount your unit from a tower and pick up within say 100 to 150 miles from Elkton FL, close to Saint Augustine and Palatka.
Call or best text 408 621-3558 before a call to discuss as I still need other items also. ( setting up a new QTH )
