Was the linytron an actual real thing or another marketing name for a precision inline tube?

[radiotvnut]

It was just a marketing term for an inline tube. The technology was no different from the inline CRT's that everybody else was using.

Interesting, I did not know that linytron was just a marketing term.

It was marketing, you know moving towards in line tubes, had to motivate people
to get a new set..... I have several Linytrons they are great sets that give long
quality life performance, I remember that one but don't have one of those yet.....

Lynitron was a play on Sonys Trinitron. I would guess
1/3 of Sony owners thought Trinitron was the brand they
had.
The sharp jug is just an early in line. Some were bonded yokes
so probably built under license from RCA. I dont remember if
any were RCA jugs ???
A local shop took on Sharp & he advertized them as "Phony
Sonys". Told people they were the same This cat was a
real promoter, a story I will tell someday.
Anyhows the shine wore off in a few years when almost every
Sharp burned up the FBT's. He had sold contracts on most &
had to eat a lot of FBT jobs plus what they damaged.

I've seen quite a few late '70's Truetone-badged Sharp color TV's that had bad flyback transformers and they were hard to find, even in the mid '90's. In the '80's models, it was often a 4th of July type of experience when the flyback went up. However, it wasn't just Sharp that had flyback problems. Panasonic TV's blew their fair share and all of the Korean TV's liked to blow them.

....and the flyback part numbers - RTRNF......and always ended in ZZ - I remember those Sharp flybacks as well. The black and white sets ate 'em just as well, but most faults were open Horizontal Oscillator coils - the windings didn't hold up in heat and humidity. We could fix them easily, if the set hadn't been run and the flyback was ate up. I guess the collector current in the Horizontal Output transistor would go to max when the oscillator quit. I do remember the symptom was a B+ resistor would get cherry red - sure sign the coil was open. Pop it out, resolder the corroded/open wire, and we were back in business, unless the fly was yellowed from internal heat. 8 bucks for a new flyback from MCM back then!

In the late 70's the distributors sent out sale flyers for CB and audio chips and transistors. In the 80s, it was flybacks, in the 90s, it was for video heads and idlers, and in the early 2000s, it was for RCA EEPROMs. Each era had it's own hot spots.
