GE MODEL 414 POWERS UP BUT NO SOUND

I picked this radio up yesterday at a yard sale for $1.00. When I plugged it in all the tubes lit up (although one (the smallest one)looks dim)), but there is no sound. Not even a bit of static. I took the radio apart and cleaned up the cabinet and dial plate, made sure the speaker connections were tight, and used a bit of wd-40 to loosen up the tuning knobs. Everything else looked to be in order although I did notice two small wax drops on the bottom metal sheeting. Appearently, where it's been stored in a hot closet or attic some time. I really didn't expect it to work because I've played with old tube radios for a few years, but I was surprised at no sound at all. Any ideas where to start on fixing it? Thanks in advance.

You need to check for B+
And that the tubes are in the right order.
If those check OK then do a check of the audio section. Start with the speaker coil first, then the speaker field coil. if they are OK, then touch your finger to the volume control and see if you get a buzz, if you do then you need to start testing each stage backward.

If you get no B+ then the power supply needs checking.

Thanks, I was looking closer at the speaker and the middle section appears to be missing. So, I'll start by trying another speaker I guess. How do I check for B+? All I know is it has something to do with voltage.
Thanks for your help.

See if you get DC voltage across C15A 50MFD cap. One lead on the positive (+) side and the other on the (-) negative side. you should read about 112Volts. On pin #7 of the tube 50C5 you should read about 105 Volts to the same negative lead on the capacitor C15A. If no voltage on that point, then turn the radio off and unplug I would suspect the audio output transformer being open, it should read (measure)285 ohms on the primary (red and blue Leads) (out of circuit). Also check (out of circuit). C14 .02MFD for a short. (0)ohms. If good it should show infinity ohms or some meter movement from zero ohms and go to infinity ohms slowly. Check for bad solder joints also. Please be careful when measuring those voltages, they can kill you.
