though I suspect this was long before XLR connectors were common.. The Cannon plug/Cannon connector was invented by James H Cannon prior to 1950. The rubber insulated version (XLR) was first produced
In addition to WLW on 700 kHz, WLWT on channel 5, and the massive Voice Of America station mid-way between Cincy and Dayton, As well as WLWD - channel 2 in Dayton, WLWC - channel 4 in Columbus, WLWI
The Henry Ultra amps have pi-network input circuits for each band. They have adjustable coils, L1-L6 on the schematic. If someone has misadjusted them, you can see high SWR. The 3K/8K Ultra does not
Of course! In any grounded grid amplifier the exciter sees both the input and output loading. Output tuning is highly influenced by the power level (maximum impedance at minimum plate current, ie, no
It's a PS--2500A, made by Watts unlimited. They seem to no longer be with us. Dr. Tim Hulick (W9QQ) became SK many years ago - I want to say 15 years ago or so. The FCC ULS shows W9QQ was canceled 2
I believe they could be used in doubler applications but not sure what to do with the center tap then. I would hi-pot test any center tap before repurposing a transformer for voltage double use. Man
