Funny that none ever trickled to my side of the Atlantic ;) I only need one when you finish one :) For now ;) I'll need a couple more later probably....

You could put the cherry on my SW cockpit with that little board ;)

Thanks !

I needed some for a couple friends that have been asking, so I went ahead and build up about a dozen spares. I'll price 'em at ~$85/ea + $10 FedEx ground shipping in the US (that's a little more than last time since I had to build 'em myself and since I was upside down on the flat shipping price last time). Same request as the last time I offered them cheap-- one per person and please don't turn around and flip 'em on eBay...

Maybe we just got lucky with our 'donor' selections (obviously we moved the yoke and rings from the original WG6100 CRT over).

Maybe some variations of the WG4xxx used 100 degree tubes and we just happened to have the right mutant versions for parts... I didn't do much other than look up the CRT P/N's and decide they were "close enough" and modify the neck key. I'd done far worse things on raster monitors when I was just starting out in the hobby-- ignorance sometimes results in success when conventional wisdom would say it's impossible. Course some things didn't work out-- my Macintosh 20" B/W display -> Vector display without changing the yoke wasn't so lucky. ;-)

I'm still not sure if that is ok or not though. And if it's a problem, whether there is a work around or if it means I'm screwed and need a new tube.

An AC setting on your multimeter will give you an idea if there is change on that signal, but I do not know what the result should be for your meter or situation. If someone here has a voltmeter and can see what reading they get on the Z-level when the board is on a set screen test that would help you figure out if yours is working properly.
