Do you remember Keith G who was one of the more
"interesting" subscribers to this group some years back?
When the drilling of small holes in CDs, and the fact that
they still played, was mentioned. He wrote: "That' nothing!
Every LP I own has a much bigger hole, and right through the
centre. The only error correction they have is an occasional
wipe with a DustBug. and they all play perfectly"

:-)
Yes met him at home once bought a brace of QUAD II's off him. Was a
real
character Keith he had a sort of bedroom with most of the gear in, all
units piled on top of each other not an audio purist by any means but
very much an enthusiast, and that in abundance!.

Yes a hi-fi enthusiast in the real sense. We never met,
but corresponded regularly. I got the impression
he was a very practical chap, good at carpentry,
and handy with the soldering iron. Quite rare
attributes for an audiophile in these plug-and-play
days.



Nil nisi bonum and all that, but there are limits.


I wonder, is there anyone these days who builds their
own equipment?. Back in the day, I knew dozens of
people who built turntable plinths, speaker cabinets,
valve amps, preamps, and transistor preamps in tobacco
tins.


Halycon days :-)


I'm holding my hand up. I learned Solidworks, and got a laser cutter
and 3D printer. And I have access any time I want to a CNC mill and a
lathe. So yes, plenty of things - mostly controlled using an Arduino
micro. Most of the electronics is for interfaces, but two months ago I
built a mic preamp specially for a high impedance mic I have.
Commercial pre-amps are all aimed at low impedance mics, and totally
unsuited to this one. Not in a tobacco tin - much better, an Altoids
tin.
