Hey guys, I was asked by a friend about his GE HJ905 (1940).

What the heck are the two light bulbs for?
I've never seen such a setup Question



Very nice cabinet. Wink
The design band that wraps around to the sides is a raised veneer - Not a Decal.



Dial and Push button eschucheons are plastic -great condition.



Tuning eye integral to dial; pushbuttons seem to work.
Whether radio works or not is unknown - Cord is cut off.

Also: Could you please guestimate a ballpark value?

Looks like a built-in dim bulb tester. Maybe they used it on 240 volts.

It's a series-filament set, and it looks like they are taking the place of the ballast tube.

Here's the schematic: http://www.nostalgiaair.org/PagesByModel/053/M0008053.pdf

Is that OME ? or Mickey Moused ?

It appears to be wired into a small Motor (is that what that is?)
that turns the Antenna ?
Or is that part of the tuning circuit? confused

ALSO: The radio is not listed in Steins Pre-War Consoles ,
could anyone hazard a guess at a Value?

Definitely an add on. The wires go into the chassis through the ballast tube socket.

There is no tuning motor.

O M G .. Embarassed

Yes! Rolling Eyes Of Course! I see that!
Oh boy...must be selective vision. Rolling Eyes .. Laughing

So...I guess that means it was probably a economical way to fix without
the price of the tube? ...and they were indeed dealing with fluctuating
voltage?
Or was it lightning protection perhaps?
The Lady told me it was her parents and it was on a farm here in Oregon.

Thanks! -Michael

Could be that the ballast tubes were not available, or that they were having problems with the tubes going bad very fast because of voltage problems. Or, maybe there was just an adventurous soul around who had read a magazine article and wanted to experiment a bit.

I doubt that it was intended to be lightning protection. You want to stop lightning BEFORE it gets in your house. Wink

Before surge protectors how were tube radios protected from lightning strikes? - Lightning rod?
ground (rod)?
I read something (and now I can't find it again Rolling Eyes ) that the ballast tube
was protection thru the antenna(?) Or am I dreamin'? Perhaps I misunderstood.

Why does this series-filament set circuit (see pic) run thru the loop antenna?

Yes, lightning rods for the house, and lightning arrestors on the antennae wire.

I don't know if a ballast tube would protect the set if lightning ever made it that far, but I seriously doubt it. There are too many nearby ground opportunities.

I have no idea why this setup is wired the way it is. Maybe it's a botched job, or someone's idea of a repair, or maybe it just appears that the wires are hooked up there? ?~shrug~? Ida no.

Oh gee... Embarassed I think I need glasses or somethin'. Rolling Eyes Upon closer examination,
That's correct- it only appears that the wires run into the antennae.

Again thanks so much! Wink

By the way, ARF'ers, this Radio is for Sale. He will only do a Local Pickup.
it is in Junction City, OR 97448. I think the cabinet is beautiful- but I already
have too many unfinished projects. Rolling Eyes PM me if interested.
