Greetings, I've been restoring a nice Harvey Wells Bandmaster to use on 80 meter AM here in northern Utah. Finally got the transmitter up to snuff. Wired up a carbon mic, and tried modulation, and the plate tuning capacitor began to put on a arcing display.
Upon inspection, I found the rotor isn't centered in between the stator plates. The gap is more in the area of 75%/25%. Thus the arcing with modulation. It's been suggested that I move the high voltage off the PA tank and just apply to the plate of the 807. I'll try that to see if the arcing will stop, but I'd rather find a replacement. If you have a junker Bandmaster, or a 140pf small variable capacitor (I'd take even higher values, can't see why it won't work) that's about 2.5 inches deep, panel mount, I'd be interested in talking to you about getting it. Thanks. Wally, AF7FH North Logan, Utah _______________________________________________ Boatanchors mailing list [email protected] https://puck.nether.net/mailman/listinfo/boatanchors
