Unloaded 18W PT Voltage
Posted: Mon 08/17/20 7:30 am
Somewhat random question, but does anyone know what the typical PT secondary voltages are for an 18W PT when fully unloaded? I usually associate 18W PT's with a 290-0-290 secondary, but I'm assuming that's when under load.
As a backstory, I'm working on building a clone of a Friedman mini. Some documentation on another forum reported that the stock PT was 310-0-310 unloaded. I'm trying to reverse engineer to sort out what PT to order for the project. Loaded B+ was 376 VDC, which appears awfully close to to what we could get with a 290-0-290 PT and solid state rectifier.
Figured, who knows random 18W specs better than you folks?
