Looking for any information at all on a Very nice complete Beckley Ralson TRF Radio. All Tubes and very nice cabinet. Looking for information on the Voltages required to fire it up. B+ is 90 V but no indications as to what the A+ voltage is. Looking for schematics and any information at all on this RARE FIND!!!! Thanks for any and all help.

The "A" supply is for tube filaments. What number tubes does it have ? 01A tubes are 5 volt filaments. A six volt A supply normally.

::Thanks Warren, I will have to pull the tubes again and check, I cleaned them the other day and looked at them but did not write the info down.

Don't know what model or year you have. Or if it takes a horn speaker. If it does take a horn type speaker, an audio output transformer and PM speaker will work most times. As with any radio, look over the electronics. Shorting wires. Past work done. Check for leaky capacitors. Ect.

I am assuming the Six volts is also DC. Do you have any schematics for a 90 Volt Supply I could build for this set by chance. Thanks for all your info.

Thanks you.
Do you have any idea of the value of this set? I have found 1 listing on ebay and so very little info on the web about it or the company. Thanks for any info you may have or can direct me to.
