I've just gone through the security vetting process and, apparently, I'm suitable for induction!
My name's Andy and I like making old televisions display a watchable picture again. Why? I don't know. I just enjoy it. I'm not a tech and have no formal electronic training but was indoctrinated into the craft by a family member years ago. I prefer B&W but they're collectors items now and I can't justify paying the premium they attract so I've gone over to the colour side. Current projects are a philps KJ-258 and KJ-658, neither of which I can find a service manual for. I'll ask about that in the TV forum when time allows. I'm don't do restorations, I just want to make them work again.

Hi Andy and welcome!

I'm a TV tech from way back who eventually became a design engineer. Now in my 70s, still working and loving it!

Those Philips models are not something I recognise, but a pic of the inside would tell me the chassis series which is what you really want to know.

K9 (delta gun)
K11 (20AX series CRT)
K12 (Door-type swing out chassis. Horribly complex)
KT2 (18 and 20 inch wing style chassis)
KT3 (14, 18, 20 and 22 inch flip down)
KL9 (nice large screen chassis)

These base models had various suffixes.e.g. "A2"

They should be one of those.

Hi Andy and Ian,

KJ258 = KT2A-3 & KJ658 = K12A-1.

Thank you Ian and MonochromeTV and I'm sorry not to reply sooner. My old TV fetish is only a hobby and I'm very much time poor at the moment!

To MonchromeTv: I'll look up the K12A chassis and get back to you on how close it is. The nearest I've found to the KJ-258 so far is a KT2 (as you've said) which is similar but, as they say, "same, same but different" I really appreciate your post. Thank you. P.S If you're into B&W, I've got a really weird Aristona (Philips) that was imported into Australia from Holland (about the late 50's but who knows when) that's been modified to run on a 240v isolation transformer with 6v3 valves (originally series string filament). I've got it working well but it's very odd!

To Mr. Robertson: These models were advertised as "designed in Australia" but I'm guessing that means the cabinet and control panel were manipulated to look nice by an Australian designer and that's about it. Both sets have a single swing out chassis (not like the duel swing out K9 etc.) with a cut out for the CRT board. They also have a PCB stuffed up behind the control panel with a mains filter / mains fuse set up and a LV power supply. I've got the KJ-258 working (long story) but it has pin cushion issues which I'll deal with at a later time. The KJ-658 is a write off as the H-out transformer is internally arching and it's in such poor general condition.

I don't wish to be impertinent or disrespectful but, as you've mentioned yourself that you're in your seventy's, could I suggest you open a thread on you're own experiences in the field? I would be really interested to hear you're TV tech history. Transitioning from radio to TV (??) to hybrid then transistor and onto colour.

Hi Andy,
I'm originally from Launceston and started with MTC Jessop's as a trainee radio serviceman,around 1966.
Very soon had a company vehicle and was out on the road repairing mainly radiograms.
Then this extended to television service. One learned very fast in those days.
Initial qualifications was by correspondence course with Australian Radio and Television College, then later with RMIT Melbourne.
Transferred to Hobart shop in 1969 to fill the boots of one of Tasmania's famous early radio and service pioneers who had retired.
Spent many years on the road, television service only, and did all the courses the manufacturer's did including Colour.
Then local technical college course on colour television theory and service.
During the early 1970's joined a local commercial television station which ran a domestic television service facility which expanded rapidly.
Up the ladder further into management and translator service.
After nearly 27 years there I eventually started my own business specialising in computer monitor repair.
Until retirement in the early 2000's.
Now enjoy electric model flying and instruction. And restoring vintage radio's.
And involved with the Hobart based Sound Preservation Society. Radio museum Bellerive.
Still have lots of manuals and spares for both radio and television repair.
So, could be helpful to you.
JJ

G'day Johnny. I'd really like to hear more about your experiences. You're email is listed as "private" (totally understandable) so I can't make personal contact. I'm interested in the early days of TV, especially in Tasmania. My Uncle built a set (with a radar tube) to bring in a Melbourne station (not sure which one) in the early days. I'm going to try and start a new thread for this as the welcome thread isn't the appropriate place. TasTelevision in the vintage TV thread.

Hi Andy, like your uncle, I built a TV set with a 5" radar tube back in 1967 for a term project.
I rebuilt the set in 2017 and also built another set using a 3" tube just for fun.

These are documented on this site in the special projects section.
Look back down the list for around 2020 for the 3" and 2017 for the 5".
You will have to look around for the different parts of the articles, the list is a bit time scattered.
The articles are pretty heavy on tech as both sets were made from scratch.
I dont have any background or training in radio or TV so the articles are full of goofs and fumbles as I made things work.

Cheers, Fred.
