Hello
I've been in hifi for 45 years and just resurrecting an old system. This forum looks to have a lot of good information.
What brought me by today was a search on an old kit from a AVA Model One. I found the kit, a "Van Alstine Phono Interface Kit" packed up in one of my collections of breadboard components. The instruction sheet was brittle but still very readable.
When I can search I'll provide more info in the appropriate subforum.
Cheers
