ok after changeing the audio transformer to no avail i chnge"d two tunning capacitors and the radio works loud and clear. go figure. you guys are great. thank you paul.

Paul: give it a good "burn-in" period before you put it back in the case. Sometimes one of the rf chokes will open up after it's been restored to working condition after so many years. I had that problem with mine after recapping and replacing both audio transformers. Played great, but the next day it was dead again. Traced it down to an open rf choke. Found a suitable replacement and all is well again. Congrats!

:Steve: thank you for the advise. i did find a bad connection on the third rf coil. i found it by accident. i was installing the cover while the radio was playing and i touched the wire going to the tuner and the radio went dead. touched the wire again and it stsarted to work again. thank you paul

up date. turned on radio today and its dead again. time to put it away and work on another project. maybe its trash time. wouldnt be the first one to go. paul

Paul: don't give up, you're almost there! I don't know if you have the early or late version, but recheck the continuity of any rf chokes, especially the one connected to the detector plate (27 tube). Another typical problem with this model is a shorted "quality condenser" (tone cap) across the input of the audio output transformer. If this shorts, the audio out from the 45's in push-pull is canceled. If you need a better schematic, you can find the modern equivalent for both versions at: http://www.atwaterkent.info/TechData/akDrawingIndex.html

Paul, have you measured the voltages at the pins of each tube as suggested? Unless you troubleshoot in a systematic manner, you are shooting in the dark.

This is not a complicated radio by any means. If you trash it, then I think there may be others in the future that you will trash without good reason.
Doug

hi. well its a early model 55 c. i dont know were the tone cap is. is it in the filter condenser can with all the other caps that i replaced?? also i would do a point to point voltage reading but my printer is down and wont be back untill next month. brand new and its dead to. anyway i got a little frustrated at the radio. need a break from it. also found a bad wire going to the manet on the speaker. the radio is producing a fait sound of spanish music. of all things.thank you. paul

I'm not sure why you need a printer to measure voltages?

hello, well im lazy and cant draw worth a darn. i print out the info so i can use it. anyway. i pulled the new caps & the tubes and the new cord off this thing and it goes out with the trash tomorrow. end of headache.!!!!!! i have a later 55 model with rot holes the size of dimes on the chassis. the radio plays great. thanks for your help and good bye untill the next time.

if you're going to trah it i could use the pwr tranny.
by the way,the quality cap is in the can with the output transformer,r/r corner covered in tar.

I believe Phil is right about the quality condenser being in the audio transformer can, but if you do have some audio it's probably okay. I wouldn't give up on it. Mine had about a dozen major problems and got them solved one by one. After recapping, mine had low and distorted audio and I found that the 2nd AF input transformer was open on one half of the secondary. This seems to be quite common on AK's. I replaced both input and output transformers with replacements from AES and got full audio without distortion. The replacements fit nicely in the original can. If yours are open, you might also want to try Norm's by-pass method at: http://www.antiqueradios.com/chrs/journal/transformers.html

ok. i didnt give up yet. i did the voltage check point to point. found little voltage between pins c2r to pins psr. that pionted to the third rf coil. pulled it out and found a tiny broken wire. fixed that problem. as far as low volume a wire on the plate of the 45 output tube came off. radio now plays loud and clear again. im glad i didnt let it beat me. now to find a cabinet to put it in.!!!!!!!! thank you

Great! Those pesky little problems are frustrating. Glad you tracked it down. Sometimes I have to walk away from a problem radio for a while, and when I come back to it the solution is right in front of me. Good luck on the cabinet hunt. There should be plenty of them out there. One will turn up.

:Steve hi again. turned on radio to see if it still worked before putting it away, and behold nothing again. put it back in the box and put it away for now. some things just dont want to be fixed. thank you for all your help. paul

I think some the finely wound coils in those radios get the "green-crude" disease after all these years, and when powered up after restoration, tend to open up. I think it's something very simple. Recheck continuity of all coils and chokes again, and let us know the result.
Steve

well hi again. just when you think things are all set, you get more stuff to fix. the 27 tube had a open filament. replaced the tube and back in buisness again. going to test this set everyday for a week. then ill put it in the box and put it away. now im transfering all the parts on the 55 late model to a good clean chassis. hope nothing else goes wrong. thank you paul
