Hi

My question is what is the best equipment to power a battery powered tube radio. Like a Atwater Kent breadboard. I would like it to have gages for voltage and amperage. Has anyone built a unit? Or know where plans are to build a power supply that can do this for a work bench. I like this kind like glasslinger has:

Years ago, I built a kit from AES. It has several B+ taps from 22V to 135V, adjustable filament voltage from 0V to at least 12V, and an adjustable C (bias) supply. One day, I plan to install mine in an enclosure, add front panel metering, and add standard pots to the front panel for voltage adjustment.

I agree--the AES supply is a decent supply. I have built and use several variants. I do not like the pine board it is built on, however I understand why they do it. Plus it has only one C-bias viltage.

I highly recommend the Arbe III. It is a well crafted supply and has several C bias voltages.

I built a power supply using some existing transformers, one back to back for a grebe radio, scroll to the end of the article:

I also built another to power what would have been a 1920's vintage battery-valve amplifier:

Again the schematics at the end of the article.
