Too good to be true?

They claim they 'refurbish' CRTs.

Looks legit so far. I found a government document regarding a name and address change.

A CRT rebuilding operation that serves all, now that's cool.

Need one for your F-16, F/A-18, or P-3C? Then yes - they do specialty CRTs. HUDs, MDUs, ADUs, DDUs, PMDUs, ECCMDs, and some sweep cart (ECM) stuff. Don't recognize the acronyms? (in Soup Nazi voice....) "No CRT for you" - all military stuff, and pricey. One UMD CRT for the older E-2C Hawkeye aircraft was ~ $21K (USD), exchange only - gotta have the dud. It had an embedded legend graticule with microchannel plate (thanks Tektronix) storage guns, and certified to 6Gs in each direction. Oh, and gold plated deflection plates - the duds were birth-to-death tracked. Freakin' O'scope size tube shipped in a 30X30X30" shipping container - one of those spring suspension kind. F/A-18A HUDs were similar - lots of mirrored phosphor elements in the CRT, aimed through optics and calibrated for deflection angle. A real bear to replace and align - we had to wait until a port visit, as catapault shots on the carrier would shake the alignment fixture. Nick (miniman82) probably can speak about the actual HUD....

Thomas and VDC made their bucks selling to the military. Spendy because it's low lot yield, and the testing alone - environmental, shock, and fluorescence/colorimetry - all very expensive to perform. Make 2000 and have a yield of 80% - who eats the 400 bad ones?? Not Uncle Sam, or Mr Trudeau - at least not directly.

Now a 21FJP22 made in the hundred of thousands with a higher yield, and lower testing threshold? Nah, not interested, them contractors...

I don't need a CRT for any one of those jets, and without a cross-reference guide to make sure one made for the F/A-18 would work in the CF-188A or CF-188B it's just too risky of an investment.

They'd work, but only with a couple of 1.95mm thick shims, approximately 26.5mm in diameter placed trans-axially along the yaw axis. Thirty shims in all, or you could just say "screw it" and spend the 30 shims on some Labatt Blue. Yeah, 30 shims would do.....


















After such, everything would seem to work just fine.

I'll just stick with the handyman's secret weapon - scratch that, I'll let it do the sticking for me, big savings there. If it's good enough for use on ex-Toronto Transit Commission unit 8041 it's good enough to mount a CRT.

......these three items, some WD-40, a vise grip, and a roll of duct tape. Any man worth his salt can fix almost any problem with this stuff alone. - Walt Kowalski

I used to watch MacGyver all the time and even I had to double-check the spelling. Surnames with a Mc/Mac prefix almost always throw me.

Thank You Jon , it's been so many years that I couldn't have bet with any certainty which way it was spelled . Anyway , kinda sad that the thread's original premise wasn't really true , lord knows I've got a CRT (just one) that I'd pay dearly to have rebuilt
