A page dedicated to this popular and highly collectable 1950s tv set.
The Bush TV22 was a popular tv set of the 1950s,so much so that it has become a style icon and is highly prized among collectors. Sets like these in good condition can fetch prices of 300 upwards depending on condition and originality.

For the first time collector these sets can seem rather daunting and safety precautions are also essential. The cathode ray tube(crt) is a vacuum device which means if you handle it roughly or drop it it could implode and cause serious injury. Voltages inside tv sets are higher too in the form of extra high tension(eht) voltages which can exceed 26kv in certain colour tv sets. In the TV22 they are not likely to exceed 8kv or so but this will give you a nasty jolt if your concentration lapses for a second!!. First anode voltages(a1) can be rather high too but once again in the TV22 should not exceed 300v.

The set was designed to run off ac and dc mains and had a complement of 15 valves and 1 cathode ray tube which was 9 inch.

They used the old 405 line system on vhf band too,which means that you will not see anything on the screen except a blank picture. The system we use now is 625 line uhf which is quite different. Also it has been brought to my attention by a fellow tv engineer that the chassis could be rendered live if the mains input plug is inserted the wrong way. To check if the chassis is "live" use a mains tester screwdriver with the neon inside and hold the tip to chassis, if the neon light up, the chassis is live and you should reverse the mains input plug on the rear of the set, many thanks to Kevin Ludlow for bringing that to my attention.
