OK we are getting closer.

Unless Monochrome has one I doubt you'll find one of those trannys and they can't be repaired because the ferrite cores are glued with epoxy, using that nifty glass-beads-in-the-mix idea of Philips' to set the core gap.

Offer of the used NT3101 still stands..

Well Ian I will probably have to get yours but what's the price your offering for it?
And what would be the payment method?
Thanks
Lance

I mean worst case scenario I may have to disconnect the high voltage winding and just make a voltage multiplyer for it but I would really like to steer away from that and keep it original.
I'm amazed by how much some of the people on this site know! Can I ask how long have some of you been doing this stuff?

I was a TV tech when I was in high school in the 60s. Made enough to buy my first car. Worked for a large service company while I did E&C Cert at night for about 10 years. Then started an electronics design company in 1976.

There wouldn't be many TVs I haven't seen before. Vintage TVs are a hobby of mine.

Re your suggestion, problem is, you'd have to remove the bad winding from the core for the tripler trick to work. Hacksaw, angle grinder, probable collateral damage. And you'll only get about 13500v max, which is a little low.

Re the NT3101, it's in an old KGH parts chassis. I believe it's OK but I'll have to strip it out and check. House painting at the moment, so this may take a while. Then I'll have to work out the necessary mods because the AFC/AGC winding on the 3101 is a lower voltage than that on the 3102.

Hopefully in the meantime you might find a suitable donor chassis with that transformer in it. Plessey-Rola made a clone of it for AWA-Thorn and it was used in the execrable last-of-the-B&W Thorn chassis, also badge engineered as AWA.

Wow Ian that explains why you know a staggering amount about this old valve gear.
I guess I might explain myself as well.
I’ve been on the soldering iron since I was about four years old (with my dad of course)
Anda couple of years ago I finally began to workout the world of thermionic emissions and valves in general. You see my dad was in his mid teens when everybody wanted to throw out valves and go germanium thus he has collected a few boxes of NOS valves from everywhere from run of the mill 6AU6 etc to some cool stuff like NOS military spec 807’s.
this of coarse has peaked my curiosity about the technology and I decided this year before I go into year 11 I’ll have a valve television project and that’s basically how I ended up with this Kreisler off eBay. It looked in good shape for its age and overall I’m very happy with it. I took a lot of convincing of my dad to finally let me get it with comments like ”where will you put it” and “what will you do with it” but anyway that’s a basic overview of how I came to find this site.
There is no need to rush and I doubt I’d find a donor chassis where I live. All the best
Lance

There are ways of using old TVs with DVD and other media players. I've posted on this site and there is an article in Silicon Chip that's my design.

They are great for watching old movies and TV programs.

Hopefully I'll be able to pull that transformer for you as part of the upcoming garage cleanup. No charge, just whatever it costs to get it to you.

Do check the CRT though. If it IS bad, all this may be for nothing - although I do have a 23" CRT in reasonable nick that should fit your set.

Email me so we can stay in touch!
