Yes indeed kan_turk (John), a 405 lines TV can be persuaded to run at 625. I too did this with my trusty Philips 17TG106U when I was in sixth form at school back in the early 70s. I had a working UHF IF strip and I connected it to the Philips with a multi-way switch so I could use the set on 405 or 625. The vision detector had to be reversed for 625. It worked really nicely and I used it for several years. The IF strip had a ratio detector (UABC80) and I just fed that into the Philips via my system switch. The sound was a big improvement over what was on offer from 405!
