Re: Can you identify these boards ?
Telefusion did have a very active, and varied, manufacturing branch to the business, "Teleng" by name.
I came across their very well made aerial distribution amps (valved, of course) when I worked for them in the late 50's, so I imagine they would already have the expertise to produce a T.V. chassis without much difficulty. Tony. |

Re: Can you identify these boards ?
I remember Teleng aerial amplifiers - didn't make the connection to Telefusion.
The rental TVs in the Seventies had Telefusion, Baird, DER and so on proudly emblazoned on the front, possibly to discourage theft. Then renting was seen as a poor man's game and they realised that having 'ordinary' sets was the way to go. Regardng the home grown sets mentioned in post #20, Tyne has been the subject of some discussion on this forum before. Berryvision - I vaguely remember these but was never lucky enough to service one. |

Re: Can you identify these boards ?
I did have a Telpro about ten years ago and have finally found the pictures of it!

Re: Can you identify these boards ?
Yes - now I remember them a bit better! In fact, I can't see how accessibilty is any better than on a Bradford. The decoder is difficult to acess for adjustment, unlike the Decca, as is the timebase and IF. The LOPT and tripler are just as difficult to replace, and the mains switch was [pretty poor as well.
The only advantage I can see is the audio/power board is easier to get to, and makes the wirewound 3.3 ohm easier to replace - and you don't run the risk of getting those infernal metal clips stuck underneath the board when working in a dark corner, which became so much brighter as the fuse blew spectacularly... |

Re: Can you identify these boards ?
Hi All,
I used to come across Telpro televisions when I worked for myself in the mid/late 70's. These were bought sets. I thought they where a much better layout than the original Decca 30 chassis They where electronically identical with the same components. It was much easier to service the power supply than on the Decca trying to get the long power/audio board out from the bottom of the chassis!! The line/frame oscillator and output stages hinged out of the cabinet making access a treat and the cabinets where more modern looking with the slider controls and varicap tuner. I went to work for Telefusion in 1982 and their standard sets where Decca Bradford 10 and 30 series and Telpro's, Decca 80's, 100's then the new 120's (Tatung). Telefusion was one of those companies that rented Sony's too. I was taken on from Sony to do Video Recorder servicing at Preston's Moorbrook St service department. It was here I learnt about Telefusions production of the Telpro Colour TV which, as said, was setup due to a chronic shortage of colour receiver production capacity in the early 70's. They where manufactured with Decca's full backing originally for the rental market then sold via Telefusions Trident outlets. I always liked the Telpro's, like the Bradford's too but the Telpro was a much neater design. Adrian |

Re: Can you identify these boards ?
Hi
I never came across the Telpro but enjoyed servicing all Decca sets which I thought were well designed chassis for servicing. 10/30 Bradfords, nice straightforward design and simple to repair. 80/88/100 chassis excellent sets for repairs and good performance. The 90 degree 80 chassis had probably the simplest line output stage ever. The Tatung 120 chassis was also good but I preferred the less common 70/90/110 chassis which had a mains isolated chassis.
