HMV 902. Replace EHT transformer.

[Mike Watterson]

Judging by the vast number of Radiospares mixed dielectric capacitors that have been used for radio and TV repairs, an expired paper capacitor didn't mean EOL.

Oh, I'd forgotten about those. Perhaps more common to see caps and droppers replaced in TVs? I've not dealt with old valve / hybrid TVs since about 1982.

I wonder how accurate the 20,000 pre-war figure is?

Also TV rental was common and I doubt rental companies would fit Band III adaptors? Also rental budgets for a certain level of time to cover cost. See car leasing today.

Certainly I was repairing 405 only sets till about 1976 and I never saw a pre-war set even in someone's house ever, but that was NI and maybe only Birmingham and London had pre-War services. I never ever saw a 405 set with a converter for Band III* either.

Also only very well off people would have bought a set before Sept 1939 and many of them would surely have "upgraded" even before 1955 and ITV?

[* In 1983 when I moved to Limerick it was common to see TVs and especially VHS with Labgear VHF to UHF converters as the service from the start in 1962 was 625 only. Later many UK TVs & VHS imported** One TX was BandI + BandIII and the poorer reception in many places TX was both on Band III. Later people in the West & Mid West had to get UHF aerials for the 3rd channel, later renamed to TG4. About 120K people of Limerick City (85K city) area had only fringe reception.
** UK DTT HD Ready sets were a blight from 2008 to well after ASO in 2012 as most didn't support H.264, used for SD from the start. Many people still have old LCD panels with setboxes. Retailers argued they were fine for Cable & Sky]
