light colorization of the internal cabinetry for "Edd"
2/24/2011 12:59:53 PMVianney
Hi to all,

Yet another restoration done.
My second one.
It's a GE-E98.

The light colorization of the internal cabinetry is due to the use of leftover paint, and i like it clean.
Some pictures below.

I like the smooth linear tuning of this GE.

My Crosley has a strange tuning that has hysteresis instead of being linear. Is that normal in some radios?
Is it because of the I.F. transformers have a third extra winding that sharpen the bandpass ?

Back to my GE.
The back of the cabinet is open for the purpose of the pictures, but it has a plywood sheet that should close the bottom part of the cabinet.
It has 5 pipe tubes (3 different height sizes, with bayonet twist lock) at the bottom of the cabinet that return the sound to the floor, then to the front of the set by a 4" aperture. Probably in the search of High fidelity....

Only one discrepancy, the set has a little steady hum that doesn't increase with the volume.
Before i replaced all the paper caps, i don't remember it has any hum at all. Otherwise i will have noticed it .
Arrrggh you told me to replace all the caps for the good!!! Now look :o)

The slight hum you get could be due to wire lead routing and grounding points. The original ground points should be where the new capacitors ground leads go. The grid cap routing and any shielding should be as original was. I notice in one of your pictures what looks like a shield ground spring covering over a grid wire. The restored view looks as this is now missing. Wires like this should be as short and direct as possible.

Ok i will recheck routing and groud points.
Not sure i did connect new caps at same original ground points. I should have replaced one cap at the time...

For the shield you see in the old picture, it was a shielded cable that use to go to a phono RCA connector and a toggle switch screwed on a little plate to the side of the cabinet. I took off at least 2 feets of this wire, and made a direct connexion to the grid cap on my audio driver tube, because i won't use any phono. I thought 2 feets less should pickup less noise.

But it's true i replaced all the grid cables, they might be longer than the original.

I check that.
Thanks
