Hello again Frank, Looks great. Well done. Mine was a doddle compared with your example. I did the extensive article reference 'LOPT Saturaration' involving the pitch overwind on a Ferguson 998T. I have also searched for it but it seems to have vanished into history. Try playing a hot air dryer on the winding 'stroking' it across until the pitch becomes soft and glossy. Several applications may be necessary to boil off the...

These pictures remind me of the early camera cables for cameras of the Marconi MkIII and later, the EMI 2001. In my BBC days, one job I had was to measure the lengths of and order the camera wall cables for Pebble Mill studios and these included runs from an apparatus room to the reception area (for Pebble Mill at One). It was always a worry that this sort of measurement was accurate enough - too short and it doesn't stretch, too long and...

The TX9 used a DST. The Philips G11, preceded the Philips K30, and Thorn TX9/10 by about 5 years.

Another HMV 904
Published (2009-12-19 12:36:00)
Btrian, thanks for the offer, but Steve Harris supplied me with a scan of the 904 manual which seems quite useable. As regards price, I too thought it was fair. If Steve had put it into the WB auction, he might have got more, but he'd have had to pay the commission, so unless it had made near the ptice of Jon's Ekco, he wouldn't have been much better off. And it could easily have gone for less, after all, the Ekco is surely much...

Vintage Christmas Window Quiz

Hi Yes, that is a Murphy TV with the A640 chassis on the left. Still think that's a Thorn 1400 on the right, but not 100% sure. Glyn

Sony video recorder question.
Published (2009-12-17 09:50:00)
If Canford can't or won't supply a CCQ plug, then your best bet is to get hold of a faulty umbilical. 20 years ago there were plenty around as they often went o/c on one strand or other and it was considered better to replace rather than try to repair. If I were looking for one, I would contact some of the second-hand professional video dealers and see if they had a discarded umbilical lying around somewhere. Try, Video Impact:...

Sony video recorder question.
Published (2009-12-17 10:56:00)
Ian many thanks for your time and trouble. I will try the contacts for the plug, and search for a Betamax** machine. As regards the proper camera then yes I quite agree that would be fine But the cheapest I have found is or was £400.00 and then a gap to over a thousand pounds, which is well beyond me. I admit that I am trying to do this as cheaply as possible and something less than perfection is OK. It's a suck it and see thing, if...

I can see a Bush TR130 (or it may be a TR230), to it's right looks like an HMV Marlborough, or something like that. And to the right of the Callers sign looks like a Murphy B818.

If it's the one I think it is, watch the PSU. It is....er....interesting. I'm at the radio station so I can't check.
Good luck with it and go back to the original arrangement.
Cheers,

other than the usual being carefull of the Mains, and as with Any laser system don`t look into the lens with it powered up, many of these devices emit large amount of IR radiation not visible to the eye, but very damaging and painless.

Not to familiar with this chassis but I would check the supply line
smoothing and decoupling. Does the effect vary with brightness levels, if
so then check capacitors especially electrolytic ones around the power
supply.

Sounds like dry joints possibly on the field timebase IC, try resoldering all of them, could of course be a dry joint elswhere in the field circuit but most likely the IC.

I dont think a recap will help you. Caps that are failing normally behave badly/erratically when they are cold and improve as they warm up. One thing that did give problems to Sony's of that era was the 33µF/160V HT smoothing caps, though I'd expect your set not to start at all if this was the case.
The chopper transformers often go dry jointed. I would suggest you remove it to see if there ...

This is only from a distant memory but I seem to remember a problem with the TX9. I believe the Atari has a 60 Hz frame scan frequency and usually 'fits' into our 50 hz system. Again from memory I don't think the TX9 has a vertical hold control. If it has, adjusting it will cure the problem but you will have to twiddle it again on live transmission. I always said the only signal that should be ...

That is a great looking 904 Ian. Well done! That tube screen does look a bit odd and I hope you have a vacuum. Regards, John.

In Dec 1989 I bought one of the last LX2802's fitted with Nicam, it is still going strong today.
Previously I had the stereo version of the 8802 (the one fitted with a 30AX tube)
The LX2802's and its 25" brother, was the last of the B&O's not to have some sort of video processing' which makes the pictures somewhat sharper and more plasticky!

Suggest you read Steve Pendlebury's excellent website:
http://www.oldtellys.co.uk/otindex.html
Especially the section on Line timebase and EHT with its safety warnings.
Transformers are not rectifiers.
Transformers cannot increase frequency.
For an introduction to transformers the wikipedia entry is pretty good: http://en.wikipedia.org/wiki/Transformer
