Where would a fella get a used CRT...for a scope?

Sphere is clearing out most of their Tek and HP parts inventory, including all the CRTs. I didn't see the tube for a 453 available on there.

Best bet would be eBay, look for a broken scope that gets some kind of trace on the screen. Loose CRTs show up occasionally, but the 453 is a popular model, and they sell quickly.

There is a CRT for a 453A on there now, but that won't fit the 453.

Thanks guys.
Yeah mine's a pre A model. I'm going to scrap this one for parts. I got four good working scopes; two of them are 50 MHz or better. No big deal unless I could get the CRT cheap and fast. I hate to scrap a classic, but maybe others may live from the donor parts.

If you haven't scrapped this one out yet, I may have a jug for you. I can't make any promises but I have a pair of scrap chassis from the 450 series in storage with relatives that might turn up what you need.

Alternatively if you _have_ scrapped yours out I might be interested in acquiring a few bits of it from you, so as to make one of my dust collectors into something that at least functions while collecting the dust. I'll check on what I need component-wise but I know I need one of the dual-shaft controls (inner shaft snapped clean off.) and two knobs, just off the top of my head.

I also have a pair of the HUGE 55x series chassis for spare parts if anyone needs... I'm the proud owner of complete functioning 551 with scope cart, and a whole herd of plugins. When someone refers to something as a "boatanchor" these are truly that. I think the main unit is about 85lbs, the power supply is another 60 easy, plus the cart and plugins. "My God. It's full of TUBES!" Doesn't even come close to expressing the thing.


I'm going to take stock of my boneyard when I find myself up in that part of the state again and give a general listing in the classifieds section.
