I am posting this for one of our members working on the passenger coaches at IRM. The electrical systems for cars with generators include a panel with an eight pin (octal base) tube that looks like it came from an old radio. But it apparently is merely a thermal delay relay encased in the tube for protection. Different relays (tubes) are used depending on voltage, time delay, and current rating. We are looking for a source for 120 volt and 38 volt tubes, replacements for OEM tubes, or tips and ideas for upgrading to use of current electronics (solid state if necessary) to have these systems operable on our cars. Two examples are a 38 volt 11 second delay normally open relay "1585 JETTRON FG"; and a 120 volt "120NO11S8" from Thermal Controls Inc. This latter part number can be interpreted as 120 volt, Normally Open, 11 second delay, 8 pin base.

Anyone have any spares for sale or trade? Other comments also helpful.

Thanks

Hi, Bob,

I don't have anything like that, but you could try a commercial outfit: Antique Electronic Supply, at www.tubesandmore.com . They have a pretty comprehensive selection of tubes and delay relays, and may even be able to give you some advice about solid-state replacements.

Good luck,

Hale-

You beat me to the punch! AEC bought out a rather impressive collection of radio parts and tubes from a gentleman I knew in St. Clair, Michigan, who ironically just assed away about a month ago. A real crotchedy old guy, he was one of these classic types who "might have it here somewhere," all depending on what his mood was. I just remember going there to get some tubes for my grandmother's PHILCO (her older brother had gone to school with guy), and seeing three walls LINED with tubes, all in their original boxes. I guess this guys dad had a store before him, so lord knows what all was there.

Evidently he was one of these rare types who new what he had and actaully let go of it, as I later saw him driving a PT Cruiser when it first came out (the guys is was now like, 87 or something), and he had moved to a fairly nice condo, after driving a beat up '75 Cordoba and living in about a 1000 square foot house for 50 years. He told me AEC (who I had never heard of before that) bought him out, after another customer of his clued them into him. He did pretty well---you could have kept a parts store going for YEARS over the internet with his collection alone.

Amprite also made these thermal delay tube timers. I used them 30 years ago. As long as it is a normally open (closes at end of time), it should not be too difficult to come up with a SS fix. You would need to know what the contacts are switching however.
