The triaxial cables are going to be "fun" I think.

I took a look inside and it appears to be very simple; just connections and switches.

Yeah... still holding off the find a good deal on the triaxials. If anyone has 4 they're looking to part with, you have a potential buyer!

Seems like the best way to find problems would be to test it (assuming
you have the triaxial cables).

One additional thought on the red sticker - could be an inventory
artifact. I've bought stuff at aerospace auctions and noticed that
many of the items had red stickers on them - the accompanying tags
often said something like surplus item from ..... project (or similar
comments).

Unfortunately I neither have the triaxial cables yet nor the 4145A, otherwise I would have done exactly that.

As to the red sticker. It wasn't in the listing so it must have been added by the seller, or the seller sent me a different unit than the one listed. I'm inclined to believe it's the former, because the unit looks similar enough to what was presented in the listing.

It’s totally grasping at straws. Fixture looks good. Tarnish on pins is not a big deal - you need to clean them probably anyway. Trying to assign meaning to that red sticker is like reading tea leaves. Seems like you got a good deal but maybe a bit of buyer’s remorse?

Actually, not really. It's reassuring to hear people don't think this is much of an issue. I'm not too worried about the cosmetics: I care much more about the functionality. I am a little annoyed at the broken fingers, but as I have a direct replacement for that fixture it's not a big deal.

Suggestions for cleaning? I posted about this a few messages ago and I was going to follow Dave's advice not to clean unless I notice problems in the fear of actually damaging something. But, if you have experience with doing this successfully I'd love to hear it.

?Hi,

I received a test fixture for a 4145A today (from Ebay, listed used) and
noticed a little red sticker on the unit that wasn't in the
listing. I've attached a picture. What does this mean?

I've seen a red sticker before on a unit I bought broken, so I sort of
assumed this meant the device was non-functional. Is this correct?

The test fixture has a few broken fingers (image also attached). I'm
less worried about this since I have a direct replacement for it, but
still annoyed.

More concerning is that the center conductor for one of the triaxial
connectors looks very blackened (third image, though unfortunately hard
to make out in the image). Is this likely to impair functionality, and
should I be concerned?

Finally, the center conductors for the BNC connectors look sick
(blackened in the same way as one of the triaxials). This should be
easier to replace.

I did not pay a "for parts or not working" price for this and the
pictures made the unit look ok with the description stating "in very
good condition" (in retrospect I should have asked for better images).

Thoughts? I'm well within my 30 day window so I can return it or ask for
a partial refund.

Thanks
Matt

Think it's worth cleaning these with deoxit? There's an amazing
restoration on the eevblog:

The poster does an amazing job of cleaning old BNC connectors.
However, I don't have the mechanical skills of that guy (he's a
machinist by trade, apparently) and I'm nervous to try it on a
triaxial connector as well as these fixture connectors that appear to be quite fragile.

I've read that thread. Amazing and beautiful work.

But honestly, if your concerns are not aesthetic, I'd not worry about it unless you actually experience trouble with the connectors.
