I agree Paul...I like the styling of these little emersons.
Thx Terry, here's one article on the cap voltage drop approach. Its example is essentially the same heater voltage requirement as mine, 25.2 volts. http://www.northlandantiqueradioclub.com...cord.shtml
But...I'm confused...36, 37, 38 and 39 tubes (a 38 is included in the article example) have DC heaters don't they?? Capacitive voltage drop circuit yields an AC voltage. Or can they run on either AC or DC since the radio schematic sure looks like the heaters would be AC if you used AC line voltage.
