mminnett Posted July 28, 2013 Posted July 28, 2013 Hello there, I have a friend who is trying to get an old tube car radio working again. I said that I would post on Stereonet to see if someone would be interested in having a go at the repair. He is happy to pay to get this done and as far as I aware the radio is the last piece of the car to be restored. If you are interested or know someone that may be please pm me and I will put you in touch. Thanks Matthew
LogicprObe Posted July 28, 2013 Posted July 28, 2013 (edited) Sounds like the guy at Batemans Bay didn't know what he was doing!...........since it came back worse than it went. By the description, the original fault was just a dry joint or dodgy valve holder..............now it sounds more severe. edit Here's the schematics for it.................you'll have to sign up to download them. http://www.radiomuseum.org/r/hudson_mot_sa39.html Edited July 28, 2013 by LogicprObe

Zaphod Beeblebrox Posted July 28, 2013 Posted July 28, 2013 Apart from valves, capacitors are the most likely items needing of replacement. Then, of course, is the dreaded vibrator. Necessary to generate the high Voltage required for operation, vibrators are so unreliable, that they are plug-in devices, just like valves. This will not likely be an inexpensive repair.
mminnett Posted July 29, 2013 Author Posted July 29, 2013 Thanks guys for all the help. I will pass on the information. Cheers Matthew
DrRick Posted March 7, 2014 Posted March 7, 2014 I fixed a lot of tube car radios when I was very young. The radios were quite old then, which is why I had them. I also converted them for AC operation and even added short wave converters to use them on the ham radio bands. There is a high failure part in the vibrator circuit known as a buffer capacitor. When they would fail the vibrator would soon fail as well. Has the buffer cap been replaced? 2
DrRick Posted March 7, 2014 Posted March 7, 2014 I forgot to add, if you send me the schematic, I would be happy to help you through the repair procedure . Peace, DrRick 2
