588 - 1937 model
This is the "before"
photo from the guy who had it listed for sale.
This radio is a new acquisition, (late June '98). It was made in 1937.
I've yet to find a schematic for it, but its got Philco-clone written
all over it from the wooden case to the circuitry. Uses 5Y3-Rectifier,
6A8-Osc/Mx, 6K7-IF, 6Q7-2 Mix/Detector and 6F6-Audio. Band coverage is
BCB and 2-7 Mcs.
Every radio has its story, and this was a "kitchen model" in the
literal sense. Granma cooked up a lot of good meals beside this radio
judging by the hardened grease covering the chassis. But there's a good
side to that being that the innards were well protected from rust.
After a good cleaning (with paint thinner), the chassis looks almost
new. I'll take kitchen grease over barn rust anytime!
It wasn't hawked on eBay as working (or non-working). I'm not brave
enough to plug in a new acquisition without some inspection. The eBay
DREAD - somebody's failed project! Lots of new components pig-tailled
in a very amateurish attempt to revive the radio. After cleaning up a
few loose wires, I plugged it in to find at least some sound if you get
close to the spkr. A little tweaking got me the local AM station on
1370 showing up on the dial at 670 or so and a 393 khz aircraft beacon
60 miles away showing up at 800! Huh?
A check of the SW band showed fairly normal operation, but I still
haven't been able to align the BCB to where its supposed to be. Suspect
the previous restorer gave up on this one. Lots more things still left
Stay tuned for more
Update 13 Aug. - Skyrover was no match for the Sparkbench. Never could
find a schematic but it turns out that somebody had tied the Osc and RF
sections of the tuning cap together. Maybe there was supposed to be a
'gimmick' capacitor there. The little diagram inside the case makes it
look that way, but I couldn't figure how it could be so. After
separating the two, she tuned right up. I think the frustrated eBay
seller put all his bad tubes in this set too because every one tested
I did some regluing and re-finished the pretty little two-tone cabinet.
This little radio has come out so perfect, electronically and visually,
that I sprang for a $15 plastic dialcover replacement. This radio now
looks like a new model on some 1937 display, just waiting to be
purchased! Its so cute!
I guess that this is a fairly rare model radio, given that no data is
available. But is sure is a classic 30s deco model that has been
revived to perfect condition. I'm kinda partial to it, even if it ain't
a Walton's radio.
