The first place I worked for after leaving school still had a myriad of the colour boom models out on rent into the early 1980's. It seems they had bought anything they could get their hands on in 71/2. We had to keep them going as they were being re rented as decontrolled sets and there was no shortage of customers then!
The Finlux peacock with it's two on off switches to catch out the engineer who had not seen one before.. very embarrassing when the customer has to show you how to turn the set on!
The very heavy 22" EMO with it's massive mains transformer and weird "secam type way of doing PAL" decoder.. EY509 line output valve.
Teleton simple PAL, metal cabinet covered in fablon "wood" (more special valves to stock)
We even had a few Tyne sets, some of the cabinets had a very homemade look about them.
less oddball was the formidable Saba telecommander with it's motorised pots and on off switch.
There was a few Kortings still around, I liked them but the worst oddball was a sort of copy of the CVC5 chassis but with a 25kv overwind on the lopt instead of a tripler. I cant remember what make they were sold as . They were a terrible thing, the LOPTx had a very short life and became really expensive. We soon gave up with them and they became the first "automatic disposal" single standard set. They got flogged off at the same time as the dual standard stuff!
The Combi Colour was another Oddball that spares ran out quickly for, the Varicap head went very "drift o tune" (pat pend) after a few years. replacements were NLA and the original was completely unrepairable as the carbon track was usually worn through or peeling off.
However armed with a CVC5 head from SENDZ, some Araldite, two small blocks of wood and a grommet to blank off the extra hole where the fine tune knob was all would be well again.
Oh happy days!
All together now...."It's crap service you get renting your clapped out set from.......(I'd better not say)
Oh happy days!
