Just added all of the photos to the photo bucket site. Both this Fielding porthole which is being restored and a few of the unknown unit I picked up over Memorial Day

Egad! what happened to that CRT? Looks like it was shipped by UP-- er, I pronounce it "OOPS"

When I removed the CRT from the chassis, a little bit of the dag peeled off. Seeing as it's a metal glass tube, I might leave it this way

ah, ok. Looked a bit like there was a massive dent in the side of it!

That's not dag, it's some sort of insulating paint. On new CRT instructions, they say to avoid touching it. That could be an early 16GP4, as the later ones they didn't seem to bother painting the glass any more. I'd just clean all that old shit off. Don't understand why they would think it necessary to insulate glass in the first place.

Thanks John, that's what I thought as the other unit I have does not have it at all, I clean it off when I re install the CRT for testing

Well, fired up the set on my variac and both the 360 and 130 volt system came up with no problem. Left the horizontal output tubes as well as the CRT out for the test. Connected the speaker and the VCR and got pretty good sound out of the speaker so most of the front end is running as well as the sound. Hopefully I'll get the CRT installed tomorrow and see if I can get a raster out of it. Gonna cut some insulator rubber sheet and cover some of the exposed CRT cone so I can minimize the chance of me having a new hair doo.

The current from the CRT is quite low - 20kV hurts like hell, but what's more dangerous is gashing your hand open on something else sharp as it's involuntarily jerked back! In all seriousness though, a healthy dose of respect for any high voltage device is good for your safety

Finally got a bit of time on the porthole and did a slow power up with the crt and got a raster at around 80 volts. Hooked up my vcr and did a little adjustment and got the picture up and running. The vertical size pot is bad as you adjust it up around mid range and the screen goes to a thin line and just past that the picture expands to super size. Rang out the pot and seems to have several dead spots so it's gonna be replaced. Overall the brightness adjustment is at about 1/3 up in the dark and the crt provides a real bright picture so guess i got lucky on this 16gp4. Now for the analyst and check for other problems.

Great progress on a great looking set! I sometimes wish here in NZ we had TV earlier than 1960...There would have been some cool looking sets around like this one! Cheers Glen

Did a bit more work on the set and couldn't get the noise out of the sound system. Also the picture was not entirely stable as I had to keep adjusting things to keep the picture good. Read a bit here and from the antique radio forum site and tried replacing the 6BN6 which cleared a bit but not much improvement. Decided to replace the tubes in the if section
as the picture stability and the static from the speaker sort of coincided. After replacing the 2nd if stage 6AU6, everything stabilized and the hum disappeared with just a bit of adjustment on the buzz control. Put that tube back into the checker and it tested ok but after a minute or so, the short light on the checker dimly lit. Guess I'm gonna have to allow the checker to heat long before saying it's a good one. Right now just letting it run and so far so good after an hour

Went ahead and finished up the TV and installed into the cabinet after doing a bit of clean up and waxing on the cabinet. I was really lucky as the restore went very well and only had a few minor bugs. This set is really going to be a great addition to my old 1922 house and cant wait to have a viewing party with some of my friends. Here are a couple of pics
