Been working on developing a ‘NEW’ octal -based RIAA preamp so this caught my eye in a giant pile of rotten paper at ye olde Sunday Flea. Click the link below to download the manual for the Fisher PR6 preamp, including schematics ETC. And check out this link for some worthy thoughts on mod’ing the circuit.
In May of 1962 “AUDIO” magazine celebrated its 15th anniversary. IIRC, AUDIO was the more consumer-facing half of what had initially been AUDIO ENGINEERING magazine; the AES Journal being created sometime in the 50s to carry the more professional articles. Anyhow, for their 15th, AUDIO asked some of the experts of the time to weigh in on THE FUTURE OF AUDIO. Harry Olson, certainly one of the greatest inventors of sound equipment who ever lived, had some comments that struck me as being incredibly prescient. I’ve never seen this reproduced anywhere, so check it out, enjoy it, share it, and take a minute to speculate on where this is all going.
