Vintage Radio Equipment, KSFO AM Transmitter Refurbishment
A collector in Austin has refurbished a massive vintage AM transmitter originally from station KSFO, modified for amateur radio use. The setup includes classic vacuum tubes and an old-fashioned mixing board with large pots and VU meters. The equipment recalls the era of "slip queuing" records using felt pads and manual gear shifts on turntables before modern digital automation.
