Hi Nick,
It's over thirty years ago so one's memory fades. The General machine might have been sourced from a wholesaler. Somehow, I don't think it came from Toshiba. You never know, the original sales invoices might still be still in existence. Even the VAT records. I hardly ever throw anything away.

Teleton was a budget brand, I had an early 70's stereo amp and matching tuner.
It was nicely made and both units certainly started my interest in hi-fi.
I passed them on to a friend who had them for many years.

I posted a Teleton TV advert, for the VX1110 on the Facebook page yesterday. Here it is again, it's from Electronics Today International (ETI) magazine, May 1972. Note the RRP of £180, a lot of money when you consider that there a job adverts in the same magazine offering salaries of £1600 to £2000 a year.

I'm not sure it helps but in the late 80's I had a General vcr for repair, supplied by an electrical wholesaler. On the rear label it said 'Fujitsu General ' and the service manual that arrived said 'Printed by Teleton Electro'.

Mikey66 · 29th Nov 2014, 10:01 pm

Well I have now fitted the 17JZ8 kindly supplied by AC/HL. I also replaced the eht cap and lead. Whilst the chassis was out I gave it a good dusting.
As you can see in the photos the set has been stored in a damp environment but the only rust I can see is underneath - no sign of any damaged components.

I gingerly powered up and got a nice sharp snowy raster, lacking in height but the tube looks good. Sadly, before I could investigate further the width began creeping in so I switched off quick fearing for the lopt.

Focus Diode · 29th Nov 2014, 10:58 pm

That's a great start Mikey. Hopefully the boost capacitor is responsible for the reducing width and not the LOPT. Several years ago I was kindly presented with an RCA Colour set modified for 625-lines, some of the valves were missing with little idea of how to obtain them, let alone what types they were. Had that been today it wouldn't have been a problem thanks to this and similar forums being available around the world. I reluctantly gave the set back to the owner unrestored as a result and don't know what happened to it.

Back to the Teleton which also has unusual valves which, interesting to note are Toshiba types. I have a Sanyo CTP370 portable which has conventional type valves, PL509 line output etc. The original valves are also Toshiba types. I'll get round to looking at it some day. I did a thread on it many years ago:

Looking forward to hear how you get on with the Teleton set.
Cheers,

I'm pretty sure the Teleton all-transistor model in my collection was made by Toshiba, so there seems to be a connection. I suspect they may have made this set as well (not only the valves used in it). Sometimes details such as a chassis label or numbers on the silkscreen or copper layer of the PCB are traceable to the original manufacturer.

Mikey66 · 19th Dec 2014, 11:17 am

Hi Brian

You were right about the boost capacitor(s). The two large grey ones in the picture on post 26. One was hot to touch after a few seconds so I replaced them both. Hopefully I will get a chance to look at the lack of height over the holidays.

Mikey66 · 19th Dec 2014, 7:26 pm

I couldn't wait. A little probing and I found C619 was pretending to be resistor.

Focus Diode · 19th Dec 2014, 8:59 pm

Excellent news Mike, well done. This will inspire me to dig out that Sanyo in the New Year and do an updated thread on it.

Cheers,
Brian

FERNSEH · 19th Dec 2014, 9:12 pm

These tiny CRT tellys are fun. I'll have to add one to my collection.
The Contec is not my set, so I'd better leave the "made in Hong Kong" label on the screen. I was asked to repair it.

I do remember Toshiba made a small TV set, can't quite remember the model type, it might have been the C680B. Superb receiver, a bit expensive though so not many were sold.

Nickthedentist · 19th Dec 2014, 9:31 pm

Wrong thread, David?!

FERNSEH · 19th Dec 2014, 11:27 pm

Hi Nick,
I realised that after I pressed the submit button. The Teleton VX1110 is an excellent TV set but it's not really a tiny CRT TV set.

David.

Heatercathodeshort · 20th Dec 2014, 12:50 am

Are you OK David?

I am on friendly terms with nurse Edith Cavall if you think you may need her assistance..

Great to see that raster on the VX1100 Mike. I think you will be surprised at the picture quality. Regards, John.

Mikey66 · 8th Feb 2015, 5:14 pm

Just an update on my little Teleton.
This afternoon I dismantled the set in order to check the tuner and IF panel.

The 15 volt supply was ok and the IF out cable was sound, so I decided to pop the side off the tuner and look for anything simple like a dry joint. It all looked ok.

To prove the fault lay in the tuner I tried an old Thorn push button unit and got some grainy images. So I think I have a duff tuner unit

Heatercathodeshort · 9th Feb 2015, 9:50 am

Check the earthing clips that earth the tuner rotor. You may find the grease has become stiff causing a bad connection stopping the oscillator. Use a tiny paint brush to remove it and relubricate with a drop of switch cleaner on the end of a 'picked out' cotton bud. Not a lot to fail in these excellent tuners. Good luck with it. John.

Mikey66 · 9th Feb 2015, 9:58 am

I'll give that a go, Thanks for the info John

Mikey66 · 9th Feb 2015, 10:27 pm

Having tried Johns suggestion of cleaning the clips on the tuner rotar to no avail. I decided to try cleaning the old Thorn tuner I had hooked up yesterday.

There is a massive improvement, I now have a clear picture and the tube looks like a good un. Thanks for the tip John.

I brought the tuner connections out through the front of the case so I could work on it with the rest of the set back inside the cabinet.

Looking into the original tuner I can make out the second transistor (2SC684) I'm guessing this is the local oscillator / mixer and the first one, a small T018 style with 4 pins, is the RF amp, but I cannot see the part number.

Does transistor replacement sound feasable?

Nuvistor · 9th Feb 2015, 10:57 pm

Looks like a diode mixer to me.
I could not do it now but I used to replace transistors in some UHF tuners.
