I've recently acquired a batch of service data for the Mitsubishi TV range covering mid 70s to early 80s, perhaps this will bring back some memories for those of you who serviced these back in the day. Sods-law, in the batch was the manual for the CT-2017BMs I recently had on the bench, all I had at the time was the R&TS circuit, in the end it wasn't required due to the ultra reliability.
Personally, I rather like the 1977 CT181B & CT205B, would quite like to find one of those, mostly it's the 80s ones that surface.

That could be the "G" or the "K" chassis.
The G chassis had two towers holding plug-in modules. The connectors became intermittent after a few years.
And the 110 degree small-neck delta CRT always had marginal convergence and purity.
The K chassis (in-line CRT) was much more reliable. Don't think I ever had to fix one.
The Q chassis that followed was around for a lot longer, but I can't recall ever having to fix one of those either.
Later sets in that list are Q chassis, the sets with 110 degree CRT are G chassis.
Our version of the CB-100B was commonly used by ENG crews as it had a battery pack.
AWA-Redifusion must have sold thousands of them, with AV In-Out conversions.
Back in the 80s we used to sell hundreds of AV In-Out conversion kits to AWA-Rediffusion because our design required less modification of the TV (Q chassis) and so was easier to fit.
In my time in TV Trade (30 years) never came across a Mitsubishi TV, let alone colour TV, for repair. Must have been extremely reliable.
The first Mitsubishi ctv sets i came across were the CT200B in late 1972, early 1973. These sets produced brilliant pics and left the UK sets for dead. Only fault i ever knew was the pbu sometimes needed replacement.
A salesman I used to work with always pronounced it "Mitsibushi" which used to do my head in!
Mitsubishi - "three diamonds".
