I recently bought a 577 D1 curve tracer with a 177 text fixture on ebay for $845. It was described as being in working condition, but it's not. The CRT has no glass in it. There is also no broken glass in the thing, so the CRT was installed this way. Otherwise, it seems to be if fair condition. Collector voltage is lower than selected by 10 to 15%, one knob is missing, and one is cracked. Otherwise, not too bad. My question is this: For the money that I've already got in it, should I buy a CRT and fix this one? Or should I try to get a refund and keep looking? In either case, any suggestions on where to look (other than ebay)?

Thanks in advance.

If I understand correctly, the CRT is smashed (I don't quite understand
what "no glass" means). For that reason, I'd ask for a refund, since there
a couple on ebay for comparable prices.

Just out of curiousity, is the A/B toggle switch lever on the 177 intact? I
have three of those and all three have the switch lever broken off.

Also, knowing what part of the world you're in might help us to suggest
other places to look.

The CRTs come from 5xxx scopes, right? If not in a rush, that could be inexpensive.

With ebay, and a seller that sends out broken when advertised as "used", you
are likely to be able to get all the money back and keep it too. Document with photos and
attach them to ebay message to the seller. You can probably negotiate to keep it all and
for less than the usual price of the 177 fixture...

If they are slow to respond, go ahead and file it as a not as described claim.
If they don't respond you get to keep all.

"No glass" means literally that - the glass vacuum envelope is gone. You can see the broken off shards at the base of the CRT. And because the broken glass is not in the shipping box or the 577 chassis, I believe it must have been installed in this condition.

The A/B switch is more or less intact. It's off center (in the off position) and not as long as original, but it does work.

Good tips, thanks. I'll look into my ebay resolution options further. I have sent a message to the seller via ebay with a picture.

Sorry, I forgot to add - I'm in Florida. I'd be willing to drive several hours to pick one up, or pay for shipping.

It helps to reference a little of the previous email's content cut and pasted into your email so we know what it's about...

Get a refund. Top dollar for a 577 with no CRT is a show stopper.
