I have an old crosley radio i got for $5 at a thrift store but i am having trouble identifying it. I think its from the late 50s but im not sure. It doesnt seem to work when i turn ehat i think to be the volum pot it cracles little bit I will get pics later. the model number is p50wen and it says chasis 5060p
the tubes are 1R5, 1t4, 1u5 it also has some hookups for batteries one "A" and 2 "B" batteries Any help would be apreciated maybe i can make a good amp out of it who knows |

Check out http://www.nostalgiaair.org/ for information.
I doubt that it would be worth any effort to make an amplifier out of it. |

Appears to be a 1957 model, since it's covered in the 1957 Beitman's manual and in a 1957 Sams folder. Schematic diagram is online at http://www.nostalgiaair.org/Resources/107/T0000107.htm

Well i tested all the tubes and they were all at about 80 100 being the highest and when i got them all back in i tried plugging it back in and it worked for a good maybe 2 minutes for the first time then just stopped. Nothing like hearing a tube radio start up makes ya feel all good and warm inside. Tomorrow i'm gona go through and see if i can find any problems. if anyone has any ideas please tell me.

How can i test them?
also on the diagram it shows one large capacitor but i'm extreamly new to reparing this type of thing so i am a little confused on what the components marked 1st I.F and 2nd I.F are. |

Also, did you try running it off batteries? Another thing to replace is the SS diode. Back in those days, they probably used a selenium diode, and those don't last forever either. Also dangerous if you poof it. Replace with a silicon diode. |
