| :Terry, :Glad I could help. If you have any trouble reading any of the other Rider data let me know. There are a total of 7 pages in Rider Volume VII for the RCA 15K, and they are all extremely small and tough to read. But with a magnifying glass I think I can make everything out OK. : :Poston :Thank Poston! Well got it working great now, no more humming. Kept the original cans in and cut the bottoms off and drilled out the interior and installed new caps into the cans. Had installed four new tubes and the magic eye and just listening to some short wave station over in Spain. I live up here is Canada and have been in the service business for some twenty years and actually just getting into tube radios for the past three years, having a great time getting these tube radios working again. Thank you. Terry. : :::Hi Terry, :::I am not surprised you hard a hard time reading the schematic. I looked it up in my original Rider volume VII, and had to use a magnifying glass to make it out. The original printing is very sharp, but extremely small. :::C85 and C86 are rated 10 mfd. C87 and C88 are rated 18 mfd. The parts list does not specify voltage ratings, but I would use 450v for all four of them. :::Thank you Poston! That's what I thought, just wanted to make sure. Both of the 10uF are shorted and the other 18uF are measuring about 14uF. Will replace all. Unit works pretty fair, should operate much better. Wonderful helpful site. Terry :::Poston ::: ::: ::::Hi all! My name is Terry and I am working on the RCA model 15K radio, unable to make out the information for the values of the four condensors down at the lower right side of this unit, they are hooked up to the 5Z4 tubes. They look to be C85, C86, C87 and the other one, they look to be 10 uF, not sure and if they are what might the voltage ratings be of each one. Thank you. Terry Onda. |
