20$ Yard sale "special" suggestions needed.....
#1

Found this one hiding in a barn at a yardsale over the weekend.......and for 20$ I couldn't say no......even if it just keeps it from the junk heap.....but I really would love to get her making some noise again.......

SO far here's what I know...

It's a Model 76...the legs have been cut, (but the previous owner thinks he may have them some where) the cabinet is structurally sound and the components look to be in reasonable shape for an 82 year old radio. I do have the tube shield, it was just removed for the picture. I also have the bezel and knobs.

But here is the issue..........the speaker and wiring harness are MIA...........so no speaker, no field coil and unless I'm very much mistaken from the looking at the schematic, no output transformer.......

So this being my first Philco and first pre 1940 radio, I through my self on the mercy of those much smarter than me lol.

How difficult will it be and where would I find the proper speaker? (Speaker and field coil Part #: 2814-b, Field Coil Part #:2850, Push Pull Output Transformer Part #: 2848)

If this is a long shot or impossible.....how feasible would it be to take a standard 8 ohm speaker, a 3200 Ohm 50 Watt resistor, and as close a matching output transformer as I can find and wire them all together?

Obviously I would love to stay the original route if at all possible.....

Thanks for you time and suggestions all. Looking forward to this one.

For the speaker I think what you are looking for is a Philco G speaker.They do appear on epay from time to time. If you want go with something newer you could use a pm speaker a choke (used to replace the field coil)and an output transformer.

Don't discount using something other than an exact replacement. As mentioned, keep an eye on ebay and also look here:

"Play Things of the Past" http://www.oldradioparts.com/

If you browse there, make sure you read the top of the page, and follow the directions.

Don't use Firefox!

You know what you're looking for, and their large speaker list is specific. You may find something.

Admiral, check my post on the model 77. Below the pictures is Ron's link to Philco replacement speakers. It appears both the 76 and 77 use the same replacement. Ergo I assume my "H" original would work for your 76. Ron can set me straight if that's wrong. Also some other parts are used in both sets. I'm going to part mine out as the cabinet is beyond salvage. Too bad the legs are different.
