John Not that much.. :no: not in that condition. zenithfan1 06-26-2009, 06:54 PM Did it get burned on the side or what?? Another one thinks they have a gold mine. Maybe a 100 but not 5. If it has a good CRT it would be worth fixing up but geeze....

John This one's more realistic: http://cgi.ebay.com/_W0QQitemZ280362556914 John Marinello 06-27-2009, 12:37 AM This one's more realistic: http://cgi.ebay.com/_W0QQitemZ280362556914 Zenith had 2 16" mahogany combo sets that year, and that one is the crappier one. The doors are fake wood grain, and the radio has 8-tubes, instead of the better 10-tube that has push buttons on either side. The 16GP4 is cracked also.

John 500 bucks , the seller is nuts ! Phil Nelson 06-27-2009, 12:00 PM I've never been able to get excited about the porthole combos. The postwar Zenith radio design is fugly. And, as with all roundies that lack a mask, you either look at a rectangular picture in the middle of the screen, or overscan the vert/horiz so that you fill the CRT and miss the corners of the picture. On the other hand, if you can't live without a combo, I guess there are uglier ones :) Phil David Roper 06-27-2009, 12:54 PM The sets are equipped with a switch which allows you a choice of normal scan, which shows in the pumpkin shape of any roundie but with unmasked black wedges above and below; and full screen, which stretches only the vertical, giving tall skinny people and egg-shaped circles.

The one that is unobtanium and usually gone to air if you can find them?? John Marinello 06-30-2009, 10:25 AM Wouldn't that be the awful 16BP4 metal-cone tube in that thing? The one that is unobtanium and usually gone to air if you can find them?? Perpetuated B.S. If you store them in a damp location long enough, they will rust, and that may cause the faceplate to crack. Note the crack in this one at the 1 o'clock position, and note how rusty the back & chassis are: http://cgi.ebay.com/_W0QQcmdZViewItemQQitemZ280362556914QQsalenotsuppo rted Also notice in the photo, one up from bottom, there is a screen above the speaker that is completely clogged up with nesting material! Whoever pulls the TV chassis is gonna be in for a big surprise! I have a pile of 50+ year-old metal tubes that are still under vacuum, and I have NO doubt that they will still be under vacuum 50 years from now. The mahogany Zenith uses the 16GP4, and the blond one uses the 19AP4. Tube TV 07-01-2009, 05:35 AM I've always wanted a porthole , but never got on local . I can imagine the $$$ one would cost to ship ,not to mention a combo ... ha1156w 07-01-2009, 02:26 PM Well what was the tube type in the Dumont sets that everyone talks about being impossible to find and prone to failure? RA-109 I think? John Marinello 07-01-2009, 02:50 PM I've always wanted a porthole , but never got on local . I can imagine the $$$ one would cost to ship ,not to mention a combo ... Update your location to something other than "At large again", and I, for one, would be happy to keep an eye open for you. John Marinello 07-01-2009, 03:27 PM Well what was the tube type in the Dumont sets that everyone talks about being impossible to find and prone to failure? RA-109 I think? Dumont made some of the best quality sets at the time. They also developed & manufactured CRTs, and most of these were unique to their sets: 12JP4, 15DP4, 20BP4, 30BP4. Dumont & others used the metal 19AP4, which is probably the one you are thinking of. Not mant rebuilders want to fool with metal CRTs either, because they require a longer oven cycle when they are rebuilt, otherwise they may implode. This is why some tubes are so scarce. If you are considering restoring a vintage television, it's best to do a little homework first, and bring a CRT tester with before you buy the set. The last I checked, B&W CRTs were a minimal of $250 (+ shipping) to have rebuilt, metal CRTs were $450. Not many sets justify that kind of expense.
