Radio Stuff from Estate Sale

I went to an estate sale about an hour away and got this lot of stuff for $100. I had to take the whole kit. Haven't identified much of the stuff, any thoughts on what some of it might be worth?

I now officially have FAR too much radio stuff in my small apartment. Five large consoles, tons of smaller stuff...some of it's going to have to go soon.



The binder is chock full of 07/1947-issue Photofact folders, Series 1-6 Complete it looks like. I see these going for $5/ea on eBay, I'll probably put some of these up for sale.



Line Cords



A nice little Radiola. Dial actuation works and everything.



Nicely organized resistors.



Junk chassis. Unidentifiable.




A-K Chassis of some sort.



Another junk chassis, no identifiable markings on it.



I don't know what this is. I got scared when I read the label after touching it, promptly went and washed my hands, wrapped it in a paper towel, and now it's sitting inside of a Tupperware coated in tin-foil for shielding. If I'm overreacting, feel free to tell me and tell me what this is. There are brushes that extend from one end and retract below a grid with little gold contacts underneath that I presume are what you're not to touch.



Misc. junk.





Neat looking, looks like the bottom might be stripped out pretty well though.





I do have the speaker. This claims to be a Philco, and has been sanded down a bit, ready to refinish.









This is kinda neat. Claims to be a Silvertone, looks like it has AM+3 Shortwave bands, a drop changer, and a record recorder. Must have been pretty high end.



Wurlitzer Organ Amplifier. Useful for the metal in the chassis, at least. The bottom looks like it's been serviced, bright and shiny caps everywhere.



Little metal-body Philco. Complete except for the back, anyway.



I think the Packard Bell casing I had, takes these innards.



Huge box of tubes. Completely unsorted. Some of them are strange types, have multiple leads on top, high numbers, etc.





RCA Victor Model C8-15. Veneer is chipped in a few places in the front but otherwise looks to be pretty well intact. Dial motion works well.



Box of can-caps, and some transformers of various types.



The front is nothing but pots, and the back is nothing but knobs and handles.



Some serious resistors in here.



A cuckoo clock and a pendulum clock.



This television, a General Electric.


So, yeah, that's what I found. I'm actually rather annoyed, honestly: my apartment is now completely full, but I'd already driven all the way up there and figure there's at least $100 worth of stuff in here.

Accepting comments, identifications, etc. on any of this stuff. Some of it will likely be making its way over to the Classifieds section a bit later, too.

I imagine I can get $200-300 from all of this when done, plus having lots of parts for my own radios. Anyone want one?

My Radio Update: 1-14-2010 to 1-22-2010

I'm getting ready to fire everything up for a live test run. I've replaced the bad power transformer with a model from a slightly higher-end Capehart Panamuse 19N3, and the new one tests good on all windings. It's a bit more powerful of a transformer than the other one was, but extra capacity never hurt anyone after all.



The new power transformer has leads on both sides of the housing; the old one was single-sided. I need to make a hole. Masked off the surroundings with painter's tape, so as not to propel metal dust into places it doesn't belong, and went at it with my Dremel.





All done:



Mounted:



Taps sorted and ready to connect:



The old power transformer was 345VCT/5.0V/6.3Vx2; the new one is 350VCT/5.0V/6.3Vx3 and higher current on each. I'm debating re-wiring the circuit to use the third 6.3V tap, but it won't hurt anything at all if left unconnected.

At this point I am almost ready to start firing everything up. I want to do the next test with the entire system hooked together -- tuner, phono, amplifier, level converter, speaker -- laid out on my table. I need to qualify the remaining capacitors in the tuner for that part, though.

My multimeter has a capacitor checker but I didn't want to shove the leads from the caps into the meter itself so I straightened out brass picture hangers to use as contact points for my alligator clip test leads. Testing a paper capacitor here, as expected it's bad.



Testing others:



Looks like I only need to replace 4 capacitors in the tuner for sure (the cardboard 0.01 uF @ 600V, and the three-section electrolytic in the can with 2x10uF @ 400V + 1x20uF @ 25V), and the capacitors in the level converter for the phono (a 2 x 20 uF @ 250V can and 4 paper capacitors), a total of 10 more capacitors to replace before it will be safe to try and fire up. Making good progress!
