I just made a discovery. The BT-20-A broadcast transmitter uses several filament transformers for the various stages. All of them are rated at 100 volts AC primary. All of the primaries pass through a voltage adjusting rheostat and volt meter to insure proper filament voltage on all tubes. So, my earlier request for a 115 vac primary filament transformer was wrong. It needs to have a 100 vac primary.
I've seen a lot of filament transformers that had 0 - 100 - 105 - 110 taps on the primary, with one secondary. They're out there, Rick. What voltages do you need? I might have one. -- Operating your AM rig without a scope is like driving our car at night without headlights.(~K4KYV) 73 = Best Regards -Geoff/W5OMR ______________________________________________________________ AMRadio mailing list List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:[email protected] To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
