Be sure someone didn't change tubes. Chassis #101 801 is battery operated. There are also 5 loctal tubes used in this battery operated chassis.

Since you have a 50A5 & other .15 amp series wired AC tubes, there should also be a 35Z3 or 35Y4? Does you radio have a line cord?

:Sivlertone about l940/41. Table, wood case slanted lower front dial. speaker above dial. data sheet inside wood case says it a battery model, but its not.. Chassis # 101 801, Tubes: 50A5, 14R7, Two 14A7 and one 7A8. Can you help with model # and schematic??
That would work but I can't remember a radio using those tubes and a selenium rectifier? Loctal tubes were around before selenium rectifiers. By the time selenium rectifiers came out loctals were no longer used, as far as I know.
It doesn't take a lot of rewiring to change over to those tubes. The filaments would need rewiring, pins #1 and #8. Most other pin connections would remain the same. Selenium rectifier & filter caps would have to be added.
Sears 101 801 shows as a battery radio. Could someone have changed or rewired the chassis. Maybe John has an idea?

:norm: this must be an AC model. has line cord and old style selemum rect.:Hi Bub

There is yet another possibility too that if Bud is in the upper midwest, he may have a radio that was modified by the same individual who very neatly modified an AA5 Arvin that I acquried a while ago to not only Loctals, but changed the unit to permeability tuning. The work was clearly done in a well equipped shop, and other than 1 original octal tube, and the obvious fact the chassis was made for a tuning condenser instead of the inductor tuning, plus the rivits were not zinc plated, but brass- It looked like factory work from Arvin. No clear reason why it was done, the original tubes were very common.
There is a small possibility that the rectifier might be a copper oxide rectifier; which usually had round fins; and by this time should have white crumbly looking residue seeping between the plates; which would have been contemporary at that time, and Sears did use them in their battery eliminators right in that time period just before, and right after the war.
Just out of curiosity, are the tubes that were in it labelled "Silvertone" or "Arvin"?

Norm/John - All tubes are stamped "Hytron". and it has slug (perm)tuning as opposed to Cap tuning. I am begining to think your right. some one has done a batt to ac conversion. many thanks for your assistance. Bud
