[Boatanchors] Testing 01A tubes

[Adam Vaughn]

 The first power supply I built for my AK 20 used a string of ten 9V batteries in series for the HV supply, with the third one tapped for the detector supply (technically a bit more than the 20V called for, but it worked just fine regardless, and the detector can handle more if you're using an 01A instead of the 00A normally used). The 6V supply was a bit more complicated; a pair of old-fashioned lantern batteries in parallel should do the trick, or maybe two paralleled sets of four D-cells in series (don't forget to wire the B- and A+ wires together). It worked, though the 6V battery didn't last too long; eventually, I lucked into an example of the ARBE-III someone else mentioned, and it's done the trick. Good luck!

Many thanks to all those who sent me an email regarding testing the 01A tube....sure do appreciate the assistance.

Now I gotta build a power supply for the AK20...I've seen several different voltages required for the receiver so there might be different versions of this radio out there.

Only kit i've seen is from Antique Radio Supply.....looks like a decent choice for not too much money.

Gotta look around the shack and in the junkbox to see if I can homebrew something to power the radio as an alternative.
