Well, the "Burning Bush" certainly sparked some good discussion.

All I can remember is back in the day when the early A823's were starting to be scrapped at my local RBM dealer, he often had a RBM valve colour set for scrap. The blunt reply when asked about them was "No sonny, it is too dangerous". Yet he would let me have A823's, no problem. This only served to increase my curiosity as to what was so dangerous about the valve variety.... so much so, I remember it clearly to this day. I can still picture the little back storage area all stacked up with goodies and sets to be chucked.....waa_gif

Can't imagine anyone wishing to have a Bush T20 in a collection, horrible sets, I know because I had loads of them on rental.  T22 was a bit better and the T26 turned out to be not too bad at all.

Nevertheless, for those needing parts, I still have a few replacement scan coil plug and socket assemblies for the T20.

I was lucky, didn't become a Bush dealer until 1972 and even by then the CTV25 was considered as not being nice.

Perhaps the later dual standard models with the EHT quadrupler were better, the Bush CTV174D. Mixed technologies in this set, valves, transistors and even an IC, the Plessey SL901 in it's earliest form.

How come no one ever coined a nickname for the Murphy sets which used the exact same chassis? confused

Like "Melting Murphy?" 

Nowhere as good as Burning Bush..... "Well, don't stand so near to the fire then !!"

Ooh-er Missus.

"Burning Bush" is a Biblical reference - Exodus 3:2 to be precise.

And the angel of the LORD appeared unto him in a flame of fire out of the midst of a bush: and he looked, and, behold, the bush burned with fire, and the bush was not consumed.

Hmm--With all this about problem sets/hot issues--They Still Cant Get It Right, even now!

Have a look at this site that deals with newish flat-screens, the carnage Inside an LED type backlit set-

Unfortunately you can't see the pictures unless you're a member of that site.

I'd just point out that unless you ask the OP first, re-using someone else's picture(s) without their permission is poor netiquette... (looks for finger-wagging smiley, fails)

So, a 'horrible set' that nonetheless kept you in business...?

The only failures my brother had on his T20 were the 910Ω resistor in the PSU and the plating on the channel selector switches which meant you couldn't reliably select a channel.

I was not that fond of any of the RBM CTV's,  the CTV25, A823 or T20. The earlier two I thought the picture did not compare to the CDA circuits, the T20 had reliability problems. Cannot comment on the later versions but they joined up with Toshiba if my memory is correct and the short time I was involved they seemed ok.

We started selling the ITT CVC20/30 sets and those had a decent picture and quite reliable.

edit the CTV25 was CDA, still not the best of pictures.

"Horrible Bush T20 TVs kept me business" Well I suppose these sets did but thankfully I had hundreds of much better sets out on rental.  I did a lot better with the Ferguson models, that is until the ICC5 came along. Best of the lot was the Toshiba sets including certain 20" Bush and Murphy models fitted with a version of the Toshiba X53B chassis.

Liked the Rank-Bush-Murphy A823 series. OK, the pictures could have been better. At least they didn't catch fire.

Interesting to note that the discount stores didn't appear until all the complicated dual-standard CTVs ceased to be marketed.

The 910 ohm resistor was part of the line output derived 12V regulator which fed the line oscillator chip, the start up supply for this chip coming via a kick start capacitor from the main psu single 200V rail first to get things going if my memory serves.

We had a fair few on-off switch failures too, usually the pull-on/push-off rotary type, they could fail permanently on more often than failing open.

So, the politest suggestion that it's rude to steal someone else's work and use it as your own is "political correctness gone mad"?

Where exactly do you live? You can hardly object to being the subject of a bit of applied breaking-and-entering. 🙂

Hee, Hee..... just trawling old posts and came across this from seven years ago, guilty as charged 🙃 I added one to my collection.

Actually, the T26 was a much better chassis. Being equipped with the 30AX CRT resulted in a much simplified circuit design and was cooler in operation compared with the earlier 20AX models.   Sold and rented very few T26 sets.  Rank-Radio-International ceased trading in 1980. At that time the company was selling off many made-for-export sets to dealers. Some models had grey and silver cabinets. Complex remote control systems.

Still have a few T20 spare parts.
