WTB: 500 pF 20 kV doorknob cap

This one is for a GE 830, and has threaded ends. The ends on this must be threaded, because it's all that supports the 1B3 socket on the chassis.

I had to rob one out of my 830 to finish up my 810, but the 830 was next on my to-do list

There you go saving my skin again!

BTW - the 810 ended up turning out nicely. Still have to tweak the picture a bit, but what a nice chassis to work on!

Friend of mine taught me a trick with adjusting horizontal frequency. Someone fiddled with the horizontal drive and frequency and I couldn't get a raster. He was able to ballpark it by arcing the lead to the plate cap of the 6BG6, and when he dialed in the largest arc, it was done.

That took balls. But it worked

We did a similar trick - used a neon light bulb, open ended, and held one lead to the plate cap of the HOT, then adjusted the sine waveform coil until it lit the brightest/most glow on both elements. It wasn't a little neon - it looked like a night-lite neon with two crescent shaped elements. Very similar I guess to the plasma globe stuff they sell in novelty shops...

Eby made a similar light bulb tester for cathode current, so they may have made (or made a similar tester) this. I have the cathode current tester - just a 47 or a 44 bulb that is placed in series with the cathode of the HOT, and adjusted for minimum glow. Worked, but crude - I always liked the Flyback Saver meter we had.

$2.13 postage....I can be like the paperboy in "Better Off Dead"

I think all that soldering lately has dulled my formerly sharp(er) wit

Let me see if one I have has threaded ends. Couldn't you thread the ends of one that is not threaded?

Not really. Maybe if I had a lathe....I'd have to turn the posts down then thread them. Fortunately Findm-Keepm has me covered on this one

Tim,

I found a GE 830 and 835 Installation Instructions Booklet - useless to me - just a 5-page booklet with descriptions of controls, pict-o-guide stuff and other info. I'm gonna get it out to you, gratis. Useless to a guy without an 830 or 835...

Cheers,
