Looks like an Emerson model 600 or 639 to me.

Paul,

I agree, this does look like a Emerson 600/639.

These often were supplied with a bakelite case that often will be destroyed in shipping, so an unattached chassis does not surprise me.

I have an unrestored one with bakelite cabinet, that I bought simply to get a good 7JP4, but I took pity on the little critter and have decided to restore it. A check resistance check indicated there was no short, so I brought it up with a variac in series with a 10 ohm, 25 watt resistor, while monitoring the voltage across the resistor and the set worked as-found!!! This won't be done again until I get ready to recap it. If you need anything measured, just holler!


By the way, there is a Sam's schematic for this set at

Wow! I have never seen this set in a bakelite case (mine is the wood model). I bet that it is really neat looking, could you perhaps post a picture?

Thanks for the replies. I did plug it in and nothing happened the tubes warmed up but no high voltage. I do have the schematics so while I'm waiting to find parts for my hallicrafter I'll start on this one.

Is my face is red! It is not bakelite. I just pulled it out of its storage box for the first time in 15 years and think I was confusing this cabinet with another set.

I've owned this 639 since the mid-1990's, when we still lived in Dayton, O. It was found in a pile of stuff that did not sell at a rural estate auction. We had missed the auction, but spotting it there, I asked if it was for sale and the guy said "Make an offer."

I said $5.00 and he replied "make it $15 and its yours", so it followed us home. At the time of purchase, I just wanted the 7JP4, but after noticing that all tubes were marked "Emerson" and the set looked 100% complete, I carefully powered it up with my variac, and much to my surprise it worked. (The CRT is unmarked, unless it is hidden under the shield or brackets.)

The set has a wooden ebonized frame around the gold plastic front. The rest of the cabinet is shiny-finished 1/4 inch plywood, with a dark oak stain that hides the grain instead of enhancing it.

Here is a picture of the same model, but the set pictured has the cabinet sides incorrectly colored.

The color of Bob's cabinet matches mine, his set shows the wood grain, while mine, you have to look closely to see the grain.

Check the low value resistor in series with the selenium rectifier. It's almost always open due to corrosion- especially if there is green at the point where the leads enter it.
