[ARC5] ARC-5 Transmitter Power Supply options/suggestions

[Radioroslyn via ARC5]

Hi Andrew
The HP-23 doesn't really have the right voltages the run the TX. Plate voltage is too high and the heater is too low. I would build one from scratch.You'll need 24vdc at a few amps, 550vdc @ 200ma, 250vdc, and 180vdc reg for the osc. There is an easy way to fabricate the rear power plug. I think most folks here would froun on modtifations to the transmitter, unless it already been chopped up. The SCR-274N transmitters run well in a stock configuration. Which model do you have?? Going to run it on CW or AM??

Hello Everyone , I was wondering about your experiences in building from scratch 
vs. modifying  something like a Heathkit Hp-23.. Would a adjustable supply be 
too risky if the voltage could accidentally be turned too high ? Any leads for 
the source of a power transformer .? Running the Xmtr at minimal power would be 
fine for me. 

Many thanks, Andrew Kopke
