Looks like this one will need a bit more work than the Webcor. Is the front photofinish or veneer?

Radio came today looks like a nice project It has a list on the bottom of the cabinet with all the caps and resistors and such on it. Should help alot.But some of the resistors say something like .0001 mica, .00005 mica, .00025 mica how many volts are they supposted to be doesnt say? the others are like .05 400 volts or .05 200 volts Which I understand but some say .005,.01, 400 volts on one line does that mean in series or parallel? Also the resistors look nothing like Ive seen before not sure how to identify them. Not sure what the light brown waxy looking thing is at the top center of the page is that has stuff soldered to it.Speaker may be shot..Should I just replace all the caps you think leave the rest alone? Pics attached---Thanks Doug

The mica caps are the flat brown rectanglular parts. They have colored dots that signify the value. Stick with 400+ volt caps & you should be fine. Here's a page that describes the color code.
http://www.vcomp.co.uk/components/cap_codes/cap_codes.htm
The resistors are dogbone style. The color of the body & painted dots will give you the value. You've got several high value resistors which will probably need to be replace as they tend to change values over time. Here's a color code for them.
http://www.nostalgiaair.org/References/rmacodes/reschart.htm
The brown waxy thing is a coil. Don't replace it unless it's bad. The speaker cone can be patched using tea bags and flexible fabric glue.
Hope this helps.

Cool thanks for helping I learn more each time and enjoy this alot! Im still not sure about though some say .005,.01, 400 volts on one line does that mean in series or parallel

Is it a dual section capacitor? Could you post a picture?

take a picture of the capacitor .005,.01, 400 v with the printing showing. That may be the biggest capacitor with the three leads. It looks like it may be a two section electrolytic on the bottom of the picture hanging over the chassis with the red-black-grey wires. If I am right then that is the one to photo the printing.

The question you asked if its parallel or in series, would be one lead is common to both caps, the others are not in parallel because they should have a coil or resistor connected between two of the capacitor leads, they are not suppose to be connected with both leads together. (If they were then it would be a parallel circuit.)

The big one is a 50-30-20 mfd electro at 150 volts

Repaired the speaker some tonight need some felt for the center I guess and black magic marker to color the coffee filter patches.Replaced the power cord with a new one was tempting to plug it in but wont until new caps and resistors are put in.Dial cord is on the way not sure how it goes on it yet but I guess Ill figure it out in time...Doug

Replaced the old broken dial cord tonight got it working fine found a similar diagram online. Rubber feet came and new grill cloth along with the new bulb for the radio.Hope the caps and resistors come before the weekend gets here. Exclamation

So the chest cold became pneumonia and I've been outta the game for a while but Im better now and this weekend I redid some of the caps and resistors and also the veneer on the radio. I used the band-it brand of veneer sticky back.It comes in a roll bought the 12x48 inch stuff in mahogany.worked great! sands and takes stain well and easy to cut .Varnishing begins monday night and some painting when all the coats of varnish are done then new grill cover new feet and as soon as I order them new knobs. The new back is in the makings soon as he has a prototype to ok, I will order it and complete the radio...Doug Smile Here's a pic

Well the outsides done I changed the way the sides meet the top.I didn't like the Black line there as you can see from my first photo at the start of this thread above.I also painted some red around the bottom and the surround of the dial . But I think Im gonna change it back to black again. All in all it really was fun to do It still needs some work inside here and there but it works for me. Thanks for all the help I received from everyone couldn't of done it without you ...Doug Very Happy P.S. The camera phone stinks sorry.
