Hi davenjax,
Congratulations - Guess you're one of those younger persons who never changed a U25, well, some of us replaced PD500s without turning the set off.
We tend now to have high pitched voices, well tellies were noisy in the late 60's with total 'killer' EHT trannies and none of that 'woofly' tripler crap.
Remember lighting a cigarette on a Thorn 3000 jelly pot lopt - had done it many times dry, before (with Rediffusion) but this time I was re-lighting one extinguished before lunch - lit up like Santa - lived to become self employed - Chris.
