I'm sure I remember picking up a lovely GEC for somebody in my FCS days...

Powered the C2219H up today, it was fizzing quite merrily, accompanied by a very strong smell of ozone. Upon inspection, nothing could be seen. At first, I thought it might be a dirty anode cap or perhaps arcing from the tripler.

I also wondered if it might be the LOPT which sits behind the tripler, but nothing from that either. I turned out the lights to see if I could track down the problem, that was no help either. On screen, the fizzing was giving interference on the test card, when I turned down the brightness, the fizzing increased, but still nothing visible!

I checked my tripler stock, and thankfully I had one, once I installed a new one, order was returned, all was well.

Good to see it's running, it needs a fair bit of trim fixing up.

The plastic wood effect covering always did wrinkle up like that after a few years, this cabinet design was carried over to the next model with the 20AX tube. With the same problem. Without completely dismantling the cabinet and recovering there isn't a lot to be done, the "Fablon" is very thick and goes brittle. Attempts to warm it up and shove it back ended in failure, for me anyway. I didn't worry about it the customers didn't seem to be bothered. I saw a lot of the delta gun solid state sets, a few weekly. This later model and subsequent models were seen far less often, maybe they didn't sell as well after the Boon was over? Or they were more reliable and just didn't come in for repair.

I would have loved one of those sets, I made a living in the 80s buying plastic cabinet ones from Mantles in chorlton cum hardy, Manchester, bought them for £25 faulty and sold then for £55 repaired and guaranteed, one thing you need to be aware of is intermittent blowing of the fuse at the top of the chassis,a poor contact in the fuse holder causes the fuse to heat up and melt it's element.

@michael-dranfield I did virtually the same. I used to buy the 20" plastic cabinet ones with broken cabinets and usually a poor tube. (The 20" was often a Toshiba and flat) Then a trip to GEC in Celta road who were flogging off the plastic cabinets cheap. A cheap re gun tube from Trent tubes (usually a few phosphor dots missing!) And you had a set that looked new! Great for slot meter rentals. Then British relay were disposing of them to a local scrap man who sold them off for peanuts. the sets often had a Mullard Colourex re-gun fitted. So back to Celta road for an IF. panel and 'Sendz' for a tuner head and you had an 'Aerial set' very cheap. in fact I bought all of the remaining stock of I.F panels from GEC... It helped that I had a mate who worked there!

@slidertogrid happy days, bought tubes myself from Trent tubes in Nottingham, an old place up some stairs with wooden floors, I very rarely got a faulty tube in the sets I bought though, I use to take a torch and look through the ventilation holes in the back, I would only buy sets that had a pink lable stuck to the CRT flare, pink lable meant re gun tube allready fitted.

Talking of Trent tubes and GEC solid states reminds me of an incident that occurred with a rental set. It was one of the aforementioned 20" slot meter rental sets. The customer had it in a bay window, apparently someone knocked on the window and his dog went mad, doing a sort of wall of death around the bay forcing the set forward. As it fell the screen caught the edge of a stone fireplace. The set went off with a huge bang, the tube completely imploded, hardly any glass was left on the rim band. Luckily with it landing face down the glass was contained but it did make me wonder how safe re gunned tubes that hadn't been re-banded were... Mullard did an ad in Television mag suggesting that tubes were safer re-banded but I wonder if any independent smaller firms did do this?

@slidertogrid I had little success with mono third part regunned CRTs For various reasons, after one came back with the gap between the rim band and glass filled with Polyfila the boss stopped getting them. Either new or rebuilt Mullard from then on depending on what the customer wanted, it helped that we didn’t rent sets.

Perhaps we chose poor regun sellers but we tried a few. Virtually all the colour CRT’s I replaced were about 3 and a half years old and replaced by Mullard under the extended guarantee, never had a quibble from them.

I may have just forgotten but I have since heard about the Ad with imploding crt but can’t recall seeing it at the time.

I'm reliably informed this set was once in your care, possibly one of your ex rentals? It has a Mullard Colourex fitted with good emissions. There is also evidence of a slot meter having been fitted, there are holes on the rear cover where it would have been. The failing tripler I replaced wasn't the original.

Maybe Chris. The sets were always labelled when out on rental but if it was disposed of afterwards rather than scrapped the rental label would have been removed and a guarantee (period) label would have replaced it. All the sets sold went with a Guarantee of some sort from 3 months to a year depending on age and price. There may be evidence of where a label had been because they did stick well...

I sold the TV business in late 2000, back then car boot sales still came up with the occasional vintage TV and radio so I sometimes went along to have a look. There was often a then fairly modern portable or two and one day I saw one with one of my shop labels on the back. The seller asked if I was interested? My other half quipped "No, He's already sold it once!" Hmmm... Maybe more than once...

De-Fabloned ready for new. The discolouration on the top front edges I where someone has tried to disguise the missing fablon with dye.

@crustytv Sounds like it could well have been one of my ex-rental slot meter sets! I thought the Fablon was tucked under the front though? And to redo it the front had to come off? Maybe I am thinking of a different model?

You're correct.

However, there's no way I'm risking trying to detach the plastic front. So I'm going to attempt to recover and come up with a solution for the overlap, luckily it only about 3mm is visible. I have a number of ideas, but not sure which I will end up going with yet.

Matching the colour fablon to the front was a complete nightmare! Still, at least I now have an unintentional wide range of fablon stock. 🙄 

My solution to the front edge was to stain the wood the same colour. Luckily I have a number of dyes in stock as I'm restoring a rare 9" PYE cabinet for The_Teleman.

The GEC refreshed.

That looks good that does! Maybe I should have just used Fablon on that Cossor radio instead of faffing around with french polish!

I normally wouldn't touch Fablon with a barge pole, I use veneer. I did consider it for this GEC, however, as Fablon is what was originally used, I thought I'd stick (oof! Bad pun) with it.

Looks good! In fact better than the original Fablon!  Is that GEC Colour badge bottom left front original? It looks like the one GEC used on the Hybrid models. I may be wrong but I don't remember this model having that badge, strange to have GEC on the front twice as well?
