Sears / Silvertone 1950's Radio

Post by selloutrr »

When my grandfather passed away my grandmother moved into a care facility and the house was sold. While the house was being packed up they found my grandfather's workshop radio packed away in the basement. It made it's way to me, where it set on the "to get to" pile for the last 6 months. I had some down time and thought I would see what it was. here are some pics.

Sears, Roebuck & Co.
Silvertone Catalog No# 225 Chassis No. 528.171 all tube AM Radio
It had a receipt tag inside it date Dec. 1952 for the Battery pack. The radio has a selector switch that allowed it to run on battery or AC power. No battery included.

The tone caps are Gudeman? they are pretty waxy it's hard to tell until I get the soldering iron out and dig in.
The tubes are 7 pin Philco 5525? I'll look closer tomorrow and update.

com'on where is your since of adventure? :D

worst case it doesn't turn on, best case it works like it was new.
Probably it would just spark a fire and you will hear voices through the speaker screaming as it burns. :twisted: Old amps like this kinda give me the hee bee gee bee's. It's cool!, I think i watched to many horror flicks as a kid.

I'll go through and make a list if I have the parts on hand i'll give it a go if it's more then $100 to get working I'll probably put it back on the shelf and enjoy it as a bookend.

Wow! It's basically a '30s design still being sold in the '50s, I think because of the battery option it uses those tubes which were obsolete in the '50s.... I had no idea.

it could be 30's the tag that has a date is only for the battery. I have no background in radio's.

does obsolete tubes = cheap replacements or $$$ hard to find.

All of those tubes should have later versions, check one of the RCA substitution lists in RCA-30 or Google it.
