I find it incredulous that both you and Marion have suggested the connection of normally earthed scopes and frequency counters to a TV chassis without first ensuring that it is fully mains isolated. Even if the set in question does have isolation the vast majority don't and to suggest such such a practice without discussing the safety issues is potentially dangerous. Since neither of you as admins/mods noticed this I have to seriously question your competence to run this forum. Keep in mind that this thread is in a public area for all to read.

Like others, I found the site by accident. I started my career in 1969 as a Rumbelows trainee engineer shortly before colour on BBC and ITV started. They were exciting times, but as a trainee I was mainly mending steam irons and toasters. Progressed onto radios, tape recorders, B/W TV's and finally Colour TV. Went in to management of workshops and finally left that side of the trade in 1991 when I went to work for an insurance company that covered domestic appliances. I retired at the end of July this year. 48 years in the trade and enjoyed every minute (and got paid too!)
Trolling through the Internet and came across your site, like many, it brought back many memories.
Had an apprentice with CES and serviced/repaired all products from Cassette Players, Radios to CTV. Fantastic place to work and very professional.
Went on to Philips Business Systems (first Word Processors), Motorola 8080 Processors and Qume Printers!
Great and interesting site. Big smile.

Hello,
First of all, many congratulations on your fantastic site which - like a previous poster - I also stumbled upon by accident. As someone who was heavilly involved with Rediffusion during the 1970's & 80's, it certainly revived a lot of memories for me.
I read with great interest your article on the Rediffusion Mk.1 CH2213. Clearly, we share a determination to keep alive the Rediffusion name and the great TV's that were maufactured by them.
You may be interested to know that I purchsed a quantity of Frequency Translators and MK.3 Conversion kits from Rediffusion Service Spares in Rochdale, prior to it's closure in 1987. At that time my family owned a leasing company that supplied HF Cable versions of RCE sets to hotels & the TV industry. These included the MK.1, MK.3, Mk.3A and the MK4 Cable-only & MK.4 Hybrid.
Like you, I still own a few Rediffusion (& Doric) HF TV's, and I retained a number of these boxes to service those sets that were not, or could not, be converted to UHF working.
Generally, I do NOT sell my equipment. However, as you are clearly a dedicated fan of these sets, if you still require a Frequency Translator or any documentation pertaining to it, please contact me.
Kind Regards

Brilliant site thanks for the nostalgic trip I was a manager for RR for about 10 years
Well Well Well...who would have thought it, finding this site by accident. I was a TV engineer in the 60s 70s and early 80s...Its good to know there is a site where we can exchange our stories. I never thought that my extensive knowledge on repairing Mono and CTVs would ever be of use again. I worked for Rediffusion, Granada, and several other large retailers. I also
had a secondhand TV business and lots of Meter sets out.....So I have worked on most of the TVs mentioned in these articles... i will keep an eye on the site Thanks

Great site, brings back memories. Good to see the Radio Rentals brochure, as our first colour set was the Baird 8742, delivered during 'Scooby Doo', up and running before the program's end. You could use a small screwdriver to fine-tune the presets through a small hole in the front of each button. It was very reliable, needing few engineer visits, unlike our previous 405/625 black and white sets, and lasted 10 years.
I used to work for the 70s colour vision it changed it name to the colour centre that is where all those oval sets came from
G11 Grundig CUC TFK Nordmende Barco
some used to come every two week to collect sets for transformation used to take about 3 weeks they were expensive at the time

I worked for an independent rental company in the mid 70's, reading the trade tales was a good reminder of those days. I loved it out on the van,15-20 calls a day most if not all fixed in the customers home. Copious amounts of tea and biscuits and they were always pleased to see you because you were going to fix their telly.

Hi
had to say thanks for a great website it brought back so many memories. I had no idea these old TV's were still out there or people such as yourself were still maintaining them. Reading through the stock faults had me remembering many of them that I thought I had forgot.
It was also good to browse through the brochures and your collection many of which I used to work on, looking at the insides brings it all back as if it were yesterday. I was in the trade when colour launched, it was an exciting time and days were never boring. A few of the older hands not many, hated colour but this was in part due to the transition. I left the trade around 77 you could see the way the job was heading.
Happy days
Eric

Hi.
This site is as good as it always was, full of a lot of excellent info.
One thing though I have been looking for is the Minimalistic Superhet Radio project that was on the forum a few years back. I was under the impression it was to be published here in its entirety.
As I've lots of time for projects due to a recent Heart operation and other further surgery I would have liked to contribute with the construction of a single valve FM set. Purely Minimalistic!

Superb tv industry site, started in service shop for traders only in Cardiff back in 88. flat screens and medical physics repair tech these days.
Renovate old wireless sets 1900 to 1980 weekends for private shop in town to keep my hand in. Still enjoy fault finding and the repair with soak test. Yes got the amateur radio bug along the way like so many tv repairers to.
73s all, Jim GW0WGN.

Hi Frank,
I did 43yrs in the trade still enjoy the work, have retired now but still do a bit, but I intend to get my 9" Bush going which has been in my attic for the last 10yrs going. When I put it up there it was still working and is only band 1 never converted to band 3. My call sign is G6IPW got my licence in 1982.
regards
Stephen

hi Frank
I have just discovered this site and found your post. I was licensed back n 1977 as G80HW and later became M0BFO!

Exactly! 60" OLED still in use in 50 years i dont think any will be in use for a start no one will have any interest in whats in side or have any idea how to fix em...
I have just found this site and am nearly reduced to tears looking back at some of the old tellies we loved and some we hated... I started work at the local CO-OP as an apprentice in 1977 and enjoyed every second.
I miss it so much and engineers now sadly no longer with us... Currently working in the medical sector my fellow engineers think im mad just because I have test card C on my monitor, most don't know what it is or what it is for. Fav tellies were Bush T20 and Fergi 3 and half thousands!

There seems to be a lot of ex-repairs engineers on this site. Your post has piqued one of my long running questions, "what killed the repairs industry"? My assumption has always been it was increasing reliability of sets coupled with increasing integration (so to repair a tv meant replacing the entire logic board which wasn't economical). It would be interesting to hear the real reasons from the horses mouth so to speak.
A little bit of background may be of interest. I got interested in the electronics of radios/tvs as a child in the late 70s. At that time in my small town there was a well known TV repair man, and there were others in the other towns nearby. I must have been the typical annoying kid asking him lots of questions. I got lots of bits off a retired repairman I got to know too at the time (pester is more likely the word).
Fast forward a couple of years to 1984 when I got to the age when I was thinking about what to do to earn a living. Repairing TVs etc seemed an interesting thing to do, and it was then I looked around and discovered all the repair shops had simply disappeared. As usual I was busily getting on with life during that time and I'd not noticed, and so I still don't know when in the interval from ~1979 - 1984 it happened.
Having noticed this we (my brother and myself) during the summer holidays of 1984 put an ad in the local paper offering to repair valve radios, in hindsight a silly thing to do, and probably breaking lots of regulations (but we were young and didn't know any of that). It was very successful especially because being naive we only asked asked for a bit more than cost price. As usual things went pear shaped due to us being well meaning in a again naive way. We got a set which needed the power section to be extensively reworked due to the lack of suitable replacement parts. The reworked power section worked perfectly, but we naively left the original circuit in place disconnected (so the set could be put back to the original design when/if the parts became available). The owner seeing the disconnected parts reconnected them somehow, blew the set up and that was the end of our repair adventures.

Hi from Frank,
Yes the 4000 was a big pain, one problem was the then new thick film high wattage resistors used. You could get a set working on the bench, give it to a rep to install and 30 min's later a phone call to say the set installed at Mr xxxx is dead on arrival. Remove the back and find a nice pile of film resistors on the bottom of the cabinet.
We as engineers always carried a spare TV set with us if going to a 4k knowing we will have to bring it back to the workshop for a long job.
P.S. Any TV engineers out there radio hams? My call-sign back in the 80's
was G8THG. I would talk to fellow TV engineers between repair jobs. Anyhow best 73's see you all soon now, M0BJN.

Hi from Frank an Ex multi-broadcast engineer from the 1980's. Great to see the old pics, I started work for multi from school aged 16 in 1974 as a trainee TV engineer. £16.00 per week, I worked through the ranks, TV3, TV2, TV1 and finally ADV Tech five years on. Great times, great sets I remember the 2K, 3K, 3.5K, 4K, 8K and 9K etc. Plus then the new vhs recorders, lots of memories keep up the good work.
Hello from Pete.
Thank you for a great site. As an ex engineer, since the early sixties I have great memories and fondness for television of the pre plasma, LCD days. I have been employed by the larger T.V. companies of the time, Radio Rentals, Dixons (Dixserve),Mastercare, Currys, Comet and various smaller local stores. I particularly appreciate the internal photographs of the equipment, rather than, as most sites, just the front appearance. All of the site is well thought out, well implemented and lots of fascinating stories and tips from other engineers. Now retired and living in Cape Town I have lost all my old contacts but still like to keep myself busy as an hobby when possible.
