My 1st Predicta

That's inspirational, was that a particular brand/color paint?

I don't have a dud, I wonder if hawkeye has one so I dont have to spend extra just to find and send one. My crt is fine, but I also would like a spare.

How the heck to you reattache the anode to the crt? right now I just have an extenstion wire up to it for testing, I could not see how to get it back on without removing the shell (and is that difficult?).

Thanks, but it doesn't work - not even close I gave up on it about a year ago. Since then I've picked up a spare chassis and CRT. I'll get back to it someday.

I used Rustoleum protective gloss enamel #7762 'sunrise red'. I don't think it's quite right though - maybe a touch darker like #7765 'regal red'

I did remove the shell. The only thing I had trouble with is removing the two little screws that hold the brass cover plate on. I've heard folks often have trouble with the spring that's underneath too.

That's a NOS 17DAP4 I picked up (my original CRT is fine too). I'm pretty sure it's a very good substitute for the original 17DRP4. You can get either one here.

hmmm mine has a 17DAP4 installed with a philco sticker and all. I wonder why the schematic calls out a 17DRP4?

Dunno - mine has the Philco sticker too, but it's a 17DRP4 (10L43 chassis). I think the specs on the two CRTs are virtually identical.

Speaker was shot to heck, found a donor from an old zenith. got the speaker back installed in the front grill, will bolt it all back together this weekend.

got it all back together, looks great, a little sync buzz that is some what tuneable. I prob should have checked the alignment curve while it was out but I just wanted to get it back togehter. I picked up some new feet for it, the orig were long gone. I could not get the anode back on, no way, so I decided to pop the shell off. Wow, what a pita... no problem getting it off but putting the retaining spring back on almost got the best of me.

At least while it was off I cleaned the CRT face and the back side of the plastic mask. Lotsa brown gunk came off the CRT screen.

Anybody have exp with polishing up plastic? this has some fine scratches that make it less than perfectly clear.

Overall it has a very decent pic, good lineairity, interlace, and focus. The CRT is a little brighter on the bottom 1/3 so dark scenes are more grey toward the bottom. Also if bold bright print is on the screen the horz before and after the print is darker.

AGC maybe?
