New Kilovac KM-13S/10 12VDC Vacuum Relay

Date Posted By Category User IP
2020-12-25********Amplifier Parts********
Continuing my excess inventory reduction of amplifier related components, I'm offering a brand new, never used, elusive,(seldom seen) Kilovac small footprint DPDT KM13/S10 antenna changeover vacuum relay. Rated at 14KV at 10 amps. 12VDC coil voltage. Measures 2" in height and 1-1/4" width. No better minimal loss changeover relay component available in so small a package. A similar unit is featured in the Surplus Sales Internet catalog posting but too outlandishly priced to repeat. Includes all mounting hardware. Specifications clearly stenciled on the relay. Absolutely clean. Solder never applied. Tested and fully operational. Ready to drop into a "serious" high power amplifier, either in an original homebrew application or a quality replacement for the typical high loss open frame DPDT relay. Requires only a 1-1/4" mounting hole. All hardware included. $185 shipped USPS w/Tracking. Pay Pal OK (w2cqm at juno.com) if sent fee-free "Friends and Family".
