Mine isn't, I just checked.

I'll need somewhere I can upload a 38MB PDF. Too big for email.

But this link may give you what you are looking for:

I did my apprenticeship back in the mid 70's as a radio tradesman and cut my teeth on the crop of colour TV's at the time.
Some were absolute monsters (Thorn 4KA!) and some were delights (Kriesler 59-1)
I mostly worked on HMV and Healing C211/212 which were horribly unreliable but performed well when working.
For my pick I would have to say the Kriesler 59-1 was the best performer and the best to work on.

Irext, same same, they were great days.
The C211/C212 were finally sorted in the end, then they stopped making them.
I think the designers had a great idea, but obviously needed more testing early in the piece.

Kriesler were a dream to service. Lots of elbow room, basic faults, no parts sourcing problems.

HMV's always scared me after a mishap when I didn't lock the chassis properly in that awful upright service position. Granted they were good to service, but a working chassis suspended upright and hopefully properly locked always scarred me a little, more so after my very expensive accident.

Right now do not have a way to get large file, but will try the link thanks.

A lot of HMV's and Healing's had their CRT's necked when the chassis came out of the hinges when locking it in the service position.
It was a great idea but poorly executed.
I used to support the chassis firmly with both hands when flipping it up but even then it would often come right out of the hinges and you'd be left holding the bag as it were.
The engineers who designed the C211/212 I think had delusions of grandeur and went for cutting edge technology borrowed from the likes of Korting, Blaupunkt and Luxor.
Just the implementation let them down.
The C221 went back to proven technology and was so much more reliable but the damage was done by then.

Blaupunkt's KC chassis had all the issues of the HMV and then some!

My colleague who used to work on them, described the experience of first switch-on after a repair as "flash-up"!

Horrible!

This is great, the vertical-chassis Admirals I was wanting to study!

I worked on a few of those Admiral's back in another life.
Access was a problem cause you had to remove the chassis before you could get at the solder side of the pcb's.
They were full of radial mounted paper caps which all needed replacement amongst other parts.
Resistors would often go high value and need replacement again needing chassis removal to gain access.
The tuner had this long shaft which went from the upper LH side of the chassis to through the front escutcheon and safety glass.
Changing channels was a real "Clunk Clunk " arrangement and the knobs frequently fell apart.
The CRT's seemed also to have a fairly short life.
All that said they worked well enough and produced a reasonable picture once overhauled.

Funny enough in the late sixties all one saw was the horizontal chassis 23" Admirals with their red caps standing on its PC boards. These appear to have been a big seller but may have been simplified compared to the original vertical 21" iteration. The only old model I saw - with the stunning picture - was around 1969 in common area of place I was rooming. It must have been a real survivor, dating back to the mid fifties, with a freakishly good CRT, as I understand Admiral were first with 21".
