My first colour TV ,when I left home was a Decca Bradford,valve,transistor TV ran it for around three years,made it out of lots of scrap ones,had a slightly green tinge to the picture due to old tube,never went wrong.When I was the apprentice,one of my jobs was keeping our workshop clean & tidy.One day
I was sweeping the floor,behind me on the soak test bench was a Bush B&W set,that had just had a new LOPTX fitted,it was running minus it's metal covers,I bent over to sweep out under the bench behind,both valve top caps bit my bum & burnt two very deep holes in my bum,bloody sore for weeks.
Oh & never discharge EHT with screw drivers,if the sets still on!Never did that again one long Philips screw driver went through workshop ceiling,got a proper beating with rolled up Daily Mirror,but no burns to hands or feet,very odd.Best of it was,the engineer in charge of me said "Jonesy,your a bloody liability,your never survive,let alone make an engineer"
A few day's later boss asks him to go up the shop & extend the main lead on the bosses electric fire,
chatting away,Big John,fits a 13 amp plug on one end of a reel of three core mains lead,the reel of cable he's got his arm through the middle,like a doughnut,yep he then preceded to put the plug in the 13 amp socket,the boss said he shot up the corridor like a rocket,pulling out off the wall the 13 amp socket,the other ends of the cable were neatly through the metal center of the reel.
I repeated word for word what he said to me about survival,which made everyone laugh,followed by another beating,with a daily newspaper.
