Any interest in these? I have 3 that appear to be NOS, no boxes, but on a Styrofoam base.

Open to offers. Would have to be FF paypal or money order if there's interest.
I have no idea what they fit or what they're worth other than a guy that wants $85 on the bay. I would rather not go to the bay.
Thanks

They appear to be the same relays in a Palomar 300a. I will check my documentation when I get home.

Hello, PLEASE let me know what you would want for them as i have 3 amps that use these and it would be good to have some spares. I do have paypal, please send me a message about what you need to get for them.
Thank you
 
This relay was used in more than one Palomar product. The one date code I see says the 36th week of 1981.

I sell a drop-in replacement-adapter module on Ebay that takes a replaceable DIP relay. If you wear it out, unplug and replace the relay. Has pins that line up with the holes in the original circuit board. Thirty-five bucks for one, sixty for two.

If anyone's interested, I can supply a link.

You'll notice a tiny hole visible above the brand-name markings. It was originally covered by a piece of tape. This was to seal the relay against circuit-board cleaning solvents. In those days, machine-soldered circuit boards were covered in flux before soldering. Washing all of it off would contaminate a relay that's not sealed. Trouble is, leaving it sealed would cause vapor to build up inside. Removing the tape after cleaning would expose the tiny hole and prevent vapors from building up inside.

Newer "sealed" relays will have a tiny tit molded on one corner that gets snapped off to expose a vent hole.

Might want to check them to see that those vapors haven't condensed onto the contact-point surfaces. When it does, the quality of the closed circuit comes and goes, makes the relay "noisy" when you tap on it.

They're all the same, they all have the tape. Found among my late father in laws belongings.

He had a ton of stuff I brought home as he worked electronics rm the 60's on until about the mid 80's.
