One of these generators is availible localy, though it's in very poor condition and priced perhaps a little high. How good are they? I have'nt seen pictures of the patterns generated. Just trying to make up my mind, I like my test equipment to be functional regardless of it's vintage. 

Thanks for looking,

John Joe.

@linescan87 I don’t know the unit, a search through WW on world radio history only gives a brief mention in the National Show reports of new models.

Have three or four of them, very difficult to get working correctly if its been played with, wlll need quite a few capacitors, that said it does produce a quite a few patterns but really only for black and white sets.

Hi Freya,

Thanks for that. This one is quite poor, missing most knobs and a bit rusty. I might give a miss. 

Thanks for the info,

John Joe.

I have one of these. It was given to me by a lecturer at collage (1977) when he packed in doing TV repairs and became a teacher. I didn't do anything with it as it was 405 line and I could see he had attempted to make it 625 line. It gives out video and Band 1 & 3 r.f. I held on to it for years and could not bring myself to dispose of it. About 15 years ago I thought I would get it going. Removed a couple of bodged in capacitors to get it back to 405 line and then worked through each stage. On the whole the problem was mostly down to the Plessey capacitors, chocolate brown devices with yellow writing. They where all leaky. These replaced and it could then be aligned and was then working correctly. I do have a manual. When I get a moment I'll add a couple of pictures. I haven't run it for over 8 years but expect it will be o.k. Missing knobs can be obtained from other Taylor r.f. generators. I did enjoy getting it going.

If this is the instrument I think it is, I thought it was designed to work on 405, 525 or 625 lines - which makes "bodged in" a bit uncharitable?

I believe it could be ordered for other standards but not seen anything but 405 line TV

I have a circuit for it but it isn't annotated, sadly.

What I also note is that these days it will be attractive to the triode brigade.

Thanks Hurty for the images, very interesting. The lack of knobs doesn't bother me to much as it has far more pressing cometic issues and as pointed out by Catho' it has certain "sexy" triodes which the majority are thankfully still present.

Anyway despite my better judgement I went ahead. I'll bang up a few pics when it arrives.

Thanks again everyone,

John Joe.

Well it landed here last week. It's not to bad or quite bad, depending on which angle you look at it from! It is a good bit down the list of things to look at so I won't get to fo anything with it soon.

Well at least the front panel looks good, apart from a few rusty screws!
