Hey, Rick - Welcome to the World-O-Drake.
Those voltages sound about right for an unloaded supply. They do drop once you connect a transmitter to the supply. 73, Steve Wedge, W1ES/4 Live free or die: Death is not the worst of evils.

When the equipment arrived one of the tubes had come out of the socket in the R-4B and it was broken so I'm waiting for a new tube. Everything looked good in the transmitter but I thought I would look at the voltages from the AC-4 before connecting things up. The voltages seem a bit high to me, but you're the experts. B+ high 769 VDC (checked at orange wire) B+ low 313 VDC (checked at yellow wire) BIAS -76 VDC (checked at green wire) 15 VAC filament voltage (checked between black and white wires) All ripple < .004 VAC Too high? v/r Rick Gunderman - WA4RG -------------------------------------------------------------------------------- _______________________________________________ Drakelist mailing list [email protected] http://mailman.zerobeat.net/mailman/listinfo/drakelist
