1927 Arborphone working
This weekend I have been working on constructing a power supply for this 1927 Arborphone. The supply provides 90 and 22.5 v. B+ and 6-volt A supplies. The radio uses all 01A tubes. This photo shows the power supply, the Arborphone, and an RCA Radiola speaker I got at a pawnshop in Alamogordo, N.M.
The yellow light on the supply indicates 110 AC, the green for 90-v dc and the red for 6 volt filament. We have been able to get all our local stations well on the radio--it's built like a tank!
