Bit more upmarket than the last MIP link
I have been watching this chap for some time now and his work just keeps getting better.
Many years ago while working at the BBC, I was amazed when the supplier of some very hard to find parts turned up with the read/record heads for an obsolete C format tape machine. This was one of those refrigerator size broadcast quality machines using 1" tape on reels. Proper hairy chested old school engineering, packed tight with unfeasibly dense boards that looked like an aerial photo of a large city, made from surface mount components. The spinning heads were fantastic jewels of precision needing to track microscopic magnetic channels on the tape surface. If I recall correctly, if you could find a spare, it would be circa £10k at a time when you could buy a house in London for that.
The engineer turned up to help us install them and I was involved in the process. He didn't speak much English but one of our engineers had hoarded a huge collection of Top of the Pops tapes he had been told to lob in a skip (instead he piled them under the floor in one of the bigger workshops). We needed some working machines! You know that scene in Pulp Fiction where Jules opens the case but you never get to see what's in it? C format tape heads made the same impression...
"Wow. Where do you get those?" I ask in awe.
"I make" he tells me in a heavy Polish accent.
Imo overthinking a problem. This is overcomming a problem often faced and cured without all those hours and materials .
