NOTES In appearence, the TV22 is similar to its predecessor, the TV12, the main external difference being the shape of the screen surround. However, behind the bakelite case is a very different circuit. The TV22 remained in production for a number of years, with some detail modifications from time to time. However there are three main versions ; in this first version the RF chassis is populated with lots of EF91's. Sometime later the RF chassis was later updated to use the new EF80 valves. Then in 1953 the TV22A was introduced which had a revised timebase chassis utilising miniature valves in place of the previous octal valves.

The TV22's main claim to fame is that it was the first British television that could be tuned by the owner to any one of the two then current BBC transmitters as well as the further three proposed channels.

An icon of early 50's bakelite sets and highly desirable today, though in its day this was one of the cheapest sets available intended for those who couldn't afford a "proper" wooden set ! [Click here for a comparison of sets from 1951]

There are far rarer Bush bakelite sets of designs visually derived from this set, but the TV22 is the most widely recognised. Regarded as a design classic, one company in the 80's produced a modern replica, the "Retrovisor".
SERVICE DATA There is a copy of the Trader Service Sheet 1091 on the Vintage Television Service Data CDROM. The original Bush manual can be downloaded below.
CURRENT STATE Remains of wooden chassis supports [11K]It may be a bakelite cabinet but there are two wooden sections on which the two chassis' are mounted. The wood is apparently a major delicacy amongst the woodworm population and you just wouldn't beleive how much sawdust fell out of the worm holes 8-o.
Remains of a wax capacitor [8K]I was also beginning to wonder if our worm friends had begun to mutate as quite a number of the wax caps appeared to be shreaded ! However it is probably more likely to be mouse damage, not that it matters as the caps would need replacing anyhow.
Bubbles in CRT glass. Owch! [2K]
The original Mullard C.R.T. has done well to survive this long withought imploding, especially when you consider there are several air bubbles in the glasswork. Not the kind of quality I'd expect from Mullard.
Line Output Transformer.

The LOPT also looks like it has seen better days, but then it is a Bush LOPT so probably wouldn't work even if it looked mint.
WHERE FOUND BVWS July Wotton Bassett auction for £170, since when prices have dropped considerably.

EBAY GUIDE This was an extremely popular and comparatively reliable set, and being relatively small was easilly tucked away into storage and forgotton about. Thus today these sets are extremely common, proved by the fact even though the entire vintage TV section on Ebay typically has only 2 pages, you can usually gaurentee at least 3 of these sets will be there at any one time. So, use these common quotes to gauge any Ebay seller.

CLAIM EBAY SELLER
"Rare" Damn Liar
"Extremely Rare" Damn Politician !
"1930's" Type "TV22" into Google. Now, what year is the set ? Right, so any Ebayer claiming 1930 is, in my opinion, a worthless un-trustworthy bone-idle twat.
£200 Starting Price 5 years ago maybe. The last one I saw in auction (that is, an auction where every one of the perhaps 100 buyers were vinate radio/TV enthusiasts) fetched £60. So, ignore the seller and buy one of the other two TV22's on Ebay instead - I was about to refer to the seller as a prat, but thinking about it maybe they are under pressure from their partner to get rid of the set but they themselves really don't want to part with it. So they've deliberatly priced it so that no-one will buy it (or if some wally does buy it the seller can buy a replacement set and spend the remaining £100 profit on something else).

Upper chassis view [30K]
The line output stage is housed in its own screened box (left, with top cover
removed). In addition the sound output valve, just to the right of the CRT, is also
screened presumably due to it's proximity to the scanning coils.
