Thank you. Yes, there is something for everyone in this hobby!

Love your testing equipment. Supreme Tube Tester, Triumph Signal Generator.

[@Davesradios]

Yes!! Good eye!! Thank you!

I love your lit, light switch, so cute. I have a 'A' battery eliminator, and a few 'b' eliminators. I recently purchased a I think 1926, very heavy Receptor 'A', 'B', 'C', battery eliminator from RCA - model 28, which I believe contain 6 tubes. I hope to get it restored and use it with a very long 1924 or 1925, 8 tube superheterodyne wooden breadboard radio. It's funny to think that in just a few years tube development was advanced enough that sets could have just 1 tube as part of the built in ac power supply. I also saw some print ads on the internet for a battery eliminator that I think was very early for radios from 1918 or there abouts, way before they became common.

Fantastic! I find your Radio Receptor supply quite interesting!
Yes,technology move along rather quickly!

@@Davesradios State of the art, didn't last long in the 1920's. Technology changed so fast. I was looking online at some early 20's radio magazines, they had some lovely radios in beautiful furniture for $200, $300 and $400 dollars and they were basically 3 or maybe 4 tubes. This was like 1922/23, a few years later most radios were 5 or 6 or 7 tubes, then when they developed ac electric radios, they priced mostly dropped a lot, comparatively to what they had been from 1920 - 1925. Of course when the depression came along, you could pick up sets for $15.00. I did see a few ads for slightly older sets for sale very cheap - I don't know if that was a gimic or not or sellers were desperate to clear out old obsolete inventory. I saw an ad for a Radiola 28 for sale for like $30.00 when it had retailed for over $200 only a few years before. I know some sellers also offered to give you a 'trade-in' credit on your old set, if you purchased one of their new sets. I like your blue speaker and your radio tester on the shelf. Things sure were made with quality back in the day, for the most part.

A = 6V filament supply. B = HT "plate" voltage at one of 90V, 100V or 135V. Ooooh - kkayyyy...

[@Davesradios]

You are correct, with ine minor correction. The bh tube provides multiple b+ voltages required for the sets operation.

[@jimhouston1605]

Very interesting. Not much information available about these old batteries. Can you please elaborate on the C battery, its significance and why we need to jumper C to B and B to A on an ARBE III to get some old AK sets to operate? Thanks!

[@Davesradios]

The jumpering is simply your return. It is akin to the negative lead on most any supply.

[@tonyperek7292]

How much were these eliminators when compared to the cost of the batteries please.?

[@Davesradios]

Good question. I beleive they were more costly initially, however when one considers the cost of replacement batteries they were cost effective. The greatest benefit is they were relatively maintenence free.

[@tonyperek7292]

@@Davesradios I wonder how much the batteries were and how much the eliminators were back then.
