Brings back memories of my DER apprenticeship in the early 1980s. As we were based on the coast I would, on occasion, reverse the detector diode so I could watch French TV (it wasn’t perfect as it was the old SECAM 819 standard, but it was better than nothing.) – We could receive France every day, with Belgium and Germany popping up during a tropo lift. The worst memory from the 1500 chassis was one day when I was adjusting the tube magnets and looking in a mirror so the results could be easily seen. As I was making some fine adjustments the chassis swung shut on my hand! The electric shock from that was nasty. I’m glad I was on a rubber mat and only had one hand attached to anything. Pulling my hand out (knee jerk reaction to being shocked) cause a load of damage to said hand: scratches, blood and gouges to the skin. Not to mention the sheer heart-thumping adrenaline rush of the whole thing – I had to sit down for an hour afterwards. Having skin contact with the top cap of the line output valve is not something I would recommend!
Hi Sean, thanks for leaving an interesting recollection from your days as an apprentice. It is often said, the reaction to a shock had more catastrophic consequences. I must admit not enjoying sticking my hands in the 3000 CTV to adjust the RGB statics, so many bitey points waiting to get you and then lacerate you as you naturally withdraw your hand in haste
