What fun!

[@georgejohnson1498]

I had the black and white version of this, and it died in 1983. It caught fire and I took it outside and threw a bucket of water into the back on the forecourt! Obviously it was not repaired. Old TVs were so unreliable [compared to valve radios], and if we think back were not very good in picture quality compared to modern ones, though I have not had an actual TV since 2002. Not missed much as I check in a few times a year when house sitting for friends. These days I don't even recognise the news-readers! Best wishes from George

[@IrishvintageTVRadio]

You're not missing much George.

[@michaeldranfield7140]

As you say the LOPT in the A823 was reliable unlike the T20 , a very nice set, shame its 26 inch , I could no longer lift one of these on my own now .

[@IrishvintageTVRadio]

They are a beast Michael!

[@RebeccaTurner-ny1xx]

Ha! Growing up in the UK in the 60s/70s, our family had a rented B&W TV that was frequently faulty and being repaired. I grew used to having to bang the top or adjust the vertical hold to get the picture steady. And the image quality was dreadful with snow, ghosting and so on. Kids these days, don't know they're born.... etc.

[@gowdsake7103]

Tants and electrolytic caps the bane of electronics

[@IrishvintageTVRadio]

Absolutely, but they gave us plenty of work.

[@DaveBrown1]

First colour TV we had, it was the Murphy version CV2215. One of the first solid state TV's. It had a nice convergence card over the panel. Over time we had to replace the Line O/P transistors (BU105's) and the trippler. Also that dropper resistor middle back went O/C. Always a bit short of chroma, but enough for the correct saturation level, I remember the firstime I set eyes on the BIG chroma decoder chip. Just remembered that blue convergence (10 ohms ??) or was it 20? pot used to burn up. Spend a bit of time setting it up and you would get a very nice picture, fixed loads of them in the day.

[@IrishvintageTVRadio]

Yes think it was 10 ohms... The single chip decoder was better. A few nice stock faults there. Also the poor frame height due to the balance pot.

[@adelestevens]

I remember my mother used to rent one of those from Telefusion in Bury(lancs) when I was a kid. It was always going on the blink, and the serviceman would come to fix it, but it self-restored just before his visit. I remember once the set was just showing static , the engineer was at the garden gate, and it worked again , and as soon as he left it stopped working!🤣

[@IrishvintageTVRadio]

Nothing like an intermittent fault, we had loads over the years. TV would come into the shop and work perfectly for a week, as soon as it was back home it would go again. Stuff of nightmares LOL.

[@analoglooney]

It was 'possessed with demons' 👿as my boss used to say. 🙂

[@robtitheridge9708]

Nice repair i allways prefered the single chip decoder. Yes having the psu back to back with the decoder was nut the best idea, if i remember the thermister used to get dry joints causing carbon tracking leading to a big flash over and good by decoder chip.

[@IrishvintageTVRadio]

Madness Rob! There was also the mod on the early ones using a matchbox and wire to move the scan drive panel out due to interference.

[@mistermikeanson]

Good spot on the dodgy cap! Anyone would have thought you'd done that before!! 😁

[@shaunrichards744]

The best red colour I have seen on a CRT was Luxor with a Toshiba picture tube. Excellent work by you on this Bush tv.

[@IrishvintageTVRadio]

Many thanks Shaun

[@wheeliebinfan1747]

Great watch Bud. I've plenty of these in stock and am collecting one in Finglas/ballymun on Thursday with a couple of others also. Hope to see you soon. Mark C

[@IrishvintageTVRadio]

Hi Mark, sounds interesting! Good to hear from you.

[@wheeliebinfan1747]

Pick up one tonight. Cabinet very poor but will be good for parts anyway. Included was a nice Siemens set from around 1984. What trim piece we're ya looking for. Was it the tube surround!

[@BrumAdam]

I like the look of that set and the picture looked really good too. Nice!

[@IrishvintageTVRadio]

Needs setting up, we'll see then. Thanks!

[@MRJWC2332]

new subby here.. i remember back in 90 whilst working in the shop i had to deliver and carry one off these 16 flights of stairs in a block of flats, due to the lifts were out of order... carry any crt make sure that the screen is in front of you and the back facing out away from you. a nice little repair there sir and i came across your channel via michael's channel, these crt's are in my book a easyer to work on and a lot better than this crap nowdays .

[@IrishvintageTVRadio]

Welcome aboard. I certainly don't envy you in that scenario!

[@marksntl7632]

Most Excellent! Thanks for sharing! I can't recall ever looking at one of these. I Do recall looking at a small amount of the Z718, T20, T22 series in the early 1980's though.....

[@Roundymooney]

Nice satisfying little repair job there Oj!

[@IrishvintageTVRadio]

Hi Roundy, thanks. They're not the best performer of their time, but they are reliable.

[@meurighailstone1999]

Wow! Nice telly. I love that era of set with Delta Gun tubes. They're a pain when it comes to convergence but once set up have a lovely look to the picture.

[@IrishvintageTVRadio]

Yes indeed, theres something special about the delta tube.

[@stephencopeland238]

Really enjoyed this episode - thank you so very much for uploading

[@IrishvintageTVRadio]

Our pleasure!

[@corinnegregory9027]

Lovely to see this big 26 inch set runnng!

[@pault4955]

We had a bush palmaster it looked something like that set. It had 6 buttons with the channel names on them. Rte 1&2 BBC 1&2 and ITV 1&2. The volume knob and the colour controls were on a sliding tray that came out with gentle push. It lived till 1993 when it got zapped by lightning.

[@PhilReynoldsLondonGeek]

When replacing an electrolytic capacitor I usually choose the closest capacitance I can get - no problem as tolerances are pretty wide - and the same or higher voltage as the original, with the only other proviso being enough room for it to fit. I would consider using an aluminium capacitor instead of tantalum, but haven't had need yet.

[@reacey]

Enjoyed this one . Thanks!

[@TheChipmunk2008]

OOO neat tuner assembly! I like it, they were so ingenious back in the day

[@johnrudd9550]

I remember reading about back injuries in Television, brought about by lifting heavy tvs..

[@TheChipmunk2008]

:) yep it was an occupational hazard :(

[@IrishvintageTVRadio]

Do you remember the special two wheel trolley they sold in Television mag, "TeleLift"?? We had one, they were quite good.

[@analoglooney]

Yes. Been there, done that. Bang and Olufson and Sony's were the worst. The customer would just stand there and watch you lug these bloody things in and out of there homes. I was 18 at the time and the sets were bigger than me.

[@analoglooney]

@@IrishvintageTVRadioYou may remember a guy called Eugene Trundell who wrote for Television magazine. I worked along side him at French's in Sussex. He devised a whole system in the workshop where the bench and the trolley were one. You would slide the set out of the van onto the trolley, the trolley would then engage in an elevator to take it to the workshop level. You would then wheel it in and it would clamp to the side bench that ran around the whole workshop. The trolley would then be your bench. When finished the reverse would happen and another set would wheel in. No Engineer ever had to lift a set from the minute it arrived to the minute it left. Pure genius. A great company to work for.

[@TheChipmunk2008]

I do not@@IrishvintageTVRadio but probably before my subscription... those old sets were heavy beasts

[@EastAngliaUK]

nice the tv should be in a museum now

[@kendom33]

I remember these from my TV shop back in the day. Before I went over to GEC

[@karbinunit]

Think we had a TV very similar if not exactly the same in our front room!!!

[@IrishvintageTVRadio]

Bet it gave little trouble.

[@jerryduhon6376]

AWESOME. THANK YOU

[@analoglooney]

I could actually hear the line oscillator running on that set through my speakers. That's a whistle I haven't heard in decades! 15.625khz. Do you ever see any ITT CVC5/8/9 sets about anymore? The picture quality on those was outstanding when they weren't on fire.

[@IrishvintageTVRadio]

I have two CVC7s here, a 26in and a 20in.

[@analoglooney]

@@IrishvintageTVRadio You greedy git. LOL. I would love to see a vid on either of those at some point please. 🙂

[@IrishvintageTVRadio]

@analoglooney They'll get there turn on the bench eventually.

[@kevvywevvywoo]

nice to see you've improved your psu arrangements for the quicko! Got a nearly new A823 on the pile here somewhere that needs fixing. Interesting band switching, never seen it this side of the irish sea. The twin tuners look very odd in there!

[@IrishvintageTVRadio]

Aye Kev, it was well overdue. Yes, many people in the UK forget about 625 line VHF. Good to hear from you.

[@kevb1816]

Result! Should tidy up nicely.

[@IrishvintageTVRadio]

Cheers Kev!

[@firsteerr]

my mum was a finisher at the factory in Enfield

[@IrishvintageTVRadio]

I'm sure she seen many changes over the years. Thanks for commenting.

[@firsteerr]

@@IrishvintageTVRadio they moved it all to the far east back in the early nineties she used to finish the wooden cabinets but of course we all went plastics so the work dried up but you shoudl see the finish on her dining table !!!

[@marcse7en]

40+ years ago, I carried an Ultra Bermuda Colour 26" set up a pair of rickety loft ladders into a dormer bedroom single handed! ... I'm now almost 62, and if you want heavy, how about the 60KG washing machine I had to lift out of its packing, and wrangle under the kitchen worktop? ... Makes a 26" TV seem lightweight! ... Then, there's the 40KG Plasma TV I had to lift single handed too!

[@IrishvintageTVRadio]

The hardship we went through!!

[@marcse7en]

@@IrishvintageTVRadio What do you mean, "Went through?" 🤣 ... I'm STILL going through it!

[@analoglooney]

The last of the Sony flat CRT's with built in subwoofers were beyond liftable too. God I dreaded those bloody things!

[@geko1022]

Ah sure ill give you a sub, I'm in good form today 😂 nice TV, i remember playing PS1 on a big old wood finished tv back in '95, think it was a Hitachi big push buttons and slider for volume, good times.

[@jimsimpson1006]

Not too bad looking inside, I was expecting a lot worse.

[@IrishvintageTVRadio]

Thanks Jim!

[@NightmarishAngel413]

i'm American, never left the country though i plan to soon what with that fascist being put in office again. I'm vaguely familiar with US TV sets from the time as it's a passing interest; so it's absolutely fascinating to see how the Irish did things back then! You've earned yourself a subscriber from across the pond, friend. I look forward to what you have in store

[@cbartley100]

From an era when the term 'Service Manual' actually meant something

[@analoglooney]

Yes, they actually wanted you to repair it. What a novel concept....

[@geoffchadwick3253]

I remember these sets pain in the arse to work, on you needed extension panel cables. just to note the was no colour oscillator they just used to "ring" the 4.433 crystal gave some funny color problems.

[@TheChipmunk2008]

Heya Jonjo, was discussing you on andy's livestream earlier, hope all is welll

[@IrishvintageTVRadio]

All good here Chip thanks!!

[@IainDavies-z2l]

Where you are in Eire can you receive UK Freeview broadcasts? In West Wales we can receive very strong FM and TV signals from Mount Leinster. Have even received FM 94.0 in Somerset/Wiltshire as fortunately we don't have any local broadcasts on that frequency.

[@IrishvintageTVRadio]

North East Coast, we can get freeview from the North. South Coast can get freeview from Wales. Thanks for commenting 🙂.

[@markdunstan8277]

I thought That the colour quality let these down the colour was very tight and always had hanover blinds Other wise not bad smart looking TV

[@IrishvintageTVRadio]

Yes Mark, a G8 or good 3500 would show them up, but they were reliable for the time.

[@sa8die]

nice TV and great look at it,.

[@Repiar.electronic.fix.2966]

Good sir

[@sammydingdong4540]

My Dad had this set it broke down from new almost every month for a couple of years , until he purchased a Sony which still worked for ten years without any problems a bit sad really.

[@steveosshenanigans]

What is the rhythmic banging in the background , its a bit of putting?

[@IrishvintageTVRadio]

That's the heater for the shed.

[@steveosshenanigans]

@@IrishvintageTVRadio Oh right Sozz ……you got to have warm shed

[@PhilReynoldsLondonGeek]

No label on the convergence panel - was this the norm with the A823B? I have some experience of the original A823.

[@IrishvintageTVRadio]

Perhaps, or maybe it fell off at some stage.

[@1sostatic]

Only a general observation ... why do we engineers find the smallest space to work in ... then fill it full of mess. ... I'm guilty too.

[@IrishvintageTVRadio]

It's all part of the course!

[@UberAlphaSirus]

Anyone else used to have a pool que remote control?

[@IrishvintageTVRadio]

Brush handle..

[@analoglooney]

Drain rod. LOL.

[@asleeds]

My Dad had a broken golf club ‘remote’ for our Bush telly. 😂

look at the size of that screen , what is it 24 26 inches ? wow you must be bobby moore !!!
