Edison Bell Model??? - BrendaAnnD - 06-24-2013

           
I bought this from someone on Antique Radio Forums. There is no model number on the set. Using the search on grillecloth.com I found what looks to be a similar chassis (but only a single band) in an Air King 77. I need to find the actual schematic if at all possible, as the set has been "restored" by someone who obviously knew little to nothing and really bolluxed up a lot of things. The entire detector and audio sections are hopelessly miswired and have parts missing.

So, does anyone recognize this thing, or have access to a schematic so that I have a hope of reconstructing it properly?

Thanks for your time.

The only Edison-Bell sets shown in Riders are all in volume 5 and I don't see any listed in my Gernsback manuals, but that cabinet sure reminds me of a Simplex I have so you might want to look at Simplex schematics.

That brand, Edison-Bell, is an odd one at least here in the states. If you give us the[/i] tube line-up we might be able to narrow it down a bit... a better pic or two of the chassis wouldn't hurt either.

Sorry, I meant to list the tube lineup when I posted. There are eight tubes, 80, 42, 42, 75, 76, 6D6, 6D6, 6A7.

Sure is a purdy lil thang, though!!! Icon_biggrin

It's one of the oldest 5 banders I've ever seen. Interesting is that Band 1 is longwave. Almost as if it's designed for the European market.

That tube lineup sounds a bit familiar. I think I have a General radio with a similar line-up and also without a model number. I am pretty sure it is a Simplex-built set.

Hello, Brenda: I have a Knight eight-tube, five band cathedral that I believe shares the same lineage as your set.

The schematics for this set are either the Simplex model W All-Wave OR the Allied P-9531 or P-9591.

If you ever get the bug to sell or trade your Edison-Bell, I would definitely be interested!

RE: Edison Bell Model??? - BrendaAnnD - 06-25-2013

Your link isn't working for some reason. The Simplex All-Wave is nowhere close to this radio (at least not the one in N-A). I can't find anything for the Allied sets you mentioned.

RE: Edison Bell Model??? - BrendaAnnD - 06-25-2013

I'm slowly rebuilding the detector and audio sections based upon the schematic mentioned above, and the radio is definately improving. I've got it down to under 20% distortion (you should have heard it before!). AGC is wonky. There's a good voltage range, but it doesn't seem to do a lot. The radio still overloads on strong signals. I have to keep my sig gen down to about 91mV or so. It's a challenge... but I LIKE a challenge. Icon_smile

RE: Edison Bell Model??? - TA Forbes - 06-26-2013

Oops, it's F-9531

RE: Edison Bell Model??? - BrendaAnnD - 06-26-2013

Thanks. Looked at that one. Looks like the W All Wave. Mine is a totally different circuit, different tube lineup, and capacitively coupled audio circuit.

This is the schematic I'm using to rebuild this poor radio. It's only a 2 bander, but everything else is very close, and at least uses the same tube set. (see bottom schematic).

Edison Bell wasn't licensed to sell radios in this country, so presumably this was an export model. Given the long-wave band, it was probably for England where Edison Bell was.

I was hoping to find it in the Wireless & Gramophone Trader, which began publishing service data on commercial sets in 1933. These were conveniently put on CDs by the British Vintage Wireless Society some years ago. Unfortunately I don't see any Edison Bell models at all.
