Motorola was one USA firm that seemed to use a lot of European tubes a lot in the early 60's. They used two 300ma series strings in a series-parallel arrangement. The 27GB5 was an example, along with the tubes previously mentioned. |

Agreed........
In the 70's Zenith CRT's were best. The chassis still held on to a lot of hand wiring til '79 so most rugged of the era. Between RCA & Zenith they sold apx half the TV's in the US. They were the two expensive brands til Sony came along. Other sets that cost as much had a tiny market share. With those you were buying a cabinet or a slick sales pitch but NOT electronics or long life. 73 Zeno LFOD ! |

I have 16" color and a 14" color Zenith from 1970 and 1972 that I could not part with and they do look pretty sharp. Also have a Sylvania CB35 from 1969 that I did not get to the bench yet. These all are barely hybrids with about a dozen tubes each.
Total agree on the 1968 Zenith 15Y6C15. Liberated one long ago from a friend's barn collection. It was a bit rusty BUT was total cake to get looking great and a guy in tech school "bought" it, never paying for it. I only compare GE Porta-color as it was a different kind of value set - fewer parts and simpler to repair, and easy-to-get parts. The customer was not expecting much, paying less accordingly. Not to forget the RCA CTC22 15" from 1967, another easy fix set that did not age so well as the Zenith. IIRC Philco, Magnavox and Admiral made their smallest color sets using the 11SP22 and 11WP22 that were in the low-focus ,porta-color league. heck, the Mag may have been Japanese. With Motorola and their cozy relationship with Matsushita, probably had one also. Never saw any of them. Two 1976 Portacolors I got, then promptly sold recently. Its all too easy to recall the days when I was the low-man on the bench that had to work on them. Just basic TV nothing more nothing less.

The Sharp built sets were the same as the Midland and Wards Airline, but the Motorola sets had better styling. |

Yes--Teleton has tint control and uses their own variation of the simple-PAL decoder design with no chroma delay-line They are reputed to work better than the equivalent age Sony non-PAL-D decoders. There's an additional Hue Adj. pot on the rear next to the frame-hold
There was one make of UK set with a full PAL-D decoder that also has a Tint-Control. ITT from CVC1 to CVC9 defo used a tint-control (On the back of dual-standard CVC1 and single-standard CVC2, later relocated to the sliders on the front of CVC5-9 sets) and was a selling point in their advertising, and maybe even later CVC20/30's had one, cant really remember-- Some of those had an 'Ideal Colour' button I recall, which switched over the user-controls to a set of internal presets.... |

If you find a Zenith set with a tube chroma demod AND SS IF. It will look better than an RCA when set up right.

Great observations here.
The tube IFs of Zeniths using the 6EJ7-6EH7 were higher gain than RCA's tube IF but the Zenith SS starting w/1970 seemed to up the whole game. Experience does bear this out: My grandparents had a 20X1C38 on an antenna in S. FLA and my fuzzy memory recalls it was a tad bit grainy oven on strong channels. But the Zenith's brightness, focus and stable HV hid that fact somewhat. I had a 1969 Zenith (16Z8C50) on Storer cable in Dallas and the picture was not as good as some SS-IF strip Zenith sets probably for this reason. Its easier to notice grainy HF video and snow on a 23" set versus a smaller set too

The picture on that set just knocked me over, it was that good! They ran the set for 14 years, with very little repairs. I did all the work on it, which was very little. |

IME--Some Tube IF Strips are outstanding. Some not so good.
The Bush TV125 B/W from late 50's early 60's has a dual-standard 405/625 line IF Strip full of EF80's/6BX6 but the set was let down in my opinion by having a tube UHF Tuner. --Bung a later type good quality Transistor Tuner in one was a match made in heaven, I swear I could get reception from Scotland if the antenna was right! Consumer grade Tube gear and UHF if not done well,--well-there you go!.. |

Thanks for sharing the pictures of the "Teleton!" Cute little Japanese set we likely would never see here in the US! I like these little Color Portables.

That is a really cool little set! I love Japanese color portables, especially oddball ones!
