If so, this eBay seller has the adapters, and lots of RCA stuff too:

Usual disclaimer - not mine, don't know or associate with seller, your mileage may vary, and caveat emptor.

Seller also has some 70 degree sockets for 21" CRTs ( I know, wrong forum)

Cheers,

Looks like a nice selection there, better organized than most. I wonder if there is any market? I have an RCA jig and bunches of adapters from various shops I've cleaned out. I'd like to find somebody that could use them.

Thanks for the link. There were no bids, and it is relisted with a Buy-It-Now price.

I have a Sylvania CK3000 jig, but I probably have most or all of these adapters, since mine came with a very good selection of them.

The shipping charge seems quite high, and the original auction shipping price was even higher.

Snapped 'em up. My Check-a-Color only came with a few adaptors, so these should make a nice addition to the collection.

Excellent!

Got them in the mail the other day, I can now test over 50 models of sets that I'll never personally own. :D

I was thinking though, it might be a good idea to make a list of all the chassis it can test. That way if someone needs to borrow it, all they have to do is drop a PM and come scoop it up.
