Title: Manual / schematic -Westrex 9200B Driver (seems unobtanium) Post by: Opcom on July 11, 2019, 11:20:59 PM Looking for the schematic or book on this beautifully made amplifier. Any help would be appreciated. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
Says "Westrex 9200B Driver" on the front. This Westrex driver amplifier uses two 8117 tubes to make about 100W, I was told. Continuously tunable 1.5 to 31 MHz using that one crank and the round dial scale. I think the input drive is very low like for a 6146 in AB1. This was used to drive a larger amp with a 4CX3000A. Nobody but nobody seems to have any data on this, or on the system it was part of. Westrex stuff - all I can find is a lot of audio gear including Western Electric (parent company), and the Westrex products made for VOX in the UK. Westrex Communications did make some Marine AM/SSB sets and a big Fax modem for weather and Navy use. It's unclear if this was before or after Litton bought the firm. Thank you Patrick KD5OEI |
