An introduction to computer audio
I started with the old gear of my parents
Triotrack turntable with ceramic cartridge.
You could flip the cartridge as it had 2 needles, one for 78 rpm and one for micro groove (33/45)
Erres radio, mono, valves
I added a big Philips speaker mounted in a piece of plywood.
Valves, vinyl, open baffle, I was a high-ender at 12!
