Good day,
I have a crosley model jc 8bk clock radio. When I bought it it did not work ( the filiments did not light), so I checked each tube and found that the 35w4 hearter was open. I replaced it with a known good one and the radio worked for about one hour the it opened the 35w4 heater eliment again. This must have been the problem before. If anyone has the schematic for this radio I would appreciate it. I'm going to replace the input caps, but I want to make sure that everything else is ok.
Thank you kindly,
Peter

Hi Peter

Crosley JC8BK is in Sam's Photofact #340-5. Your local library should be able to get this information. Sam's also sells it by calling 800 428-7267.

Replace the electrolytic filter caps. These can short over time and blow the 35W4. Also if your radio has a lamp be sure it's good. It's part of the circuit. If open the 35W4 can go bad.
