Default Re: The Audiophoolery Thread.

Interestingly, the discussion about lecturers and the such takes me back. I really struggled at Uni (Imperial) and then Poly (Lanchester). But realised that practically I understood how stuff worked. For example I was 'taught' twice how transistors worked, all being about voltage gain, with particular resistors. As soon as I was shown that actually they were essentially a current amplifier I got it.

But it also reminds me of a long lost friend who gave up on electronics because he didn't get transistors and how 'holes' transferred. He had been quite active previuosly having built a TV using a ministry scope, but got an upside down picture becuase of a misconnection, this in the days where transmission was still crystal palace. Later, but before transistors, he and a group of friends were also experimenting with recording video on swedish iron wire.

When he gave up after transistorisation, he got back into motorbikes, supprting his son in TT racing.

I still have some of his radio servicing books that he gave me 30+ years ago.
