I just picked up a sunn 312...
« on: April 20, 2006, 03:44:29 pm »
and was wondering if there was any way to tell how old it is.  I bought it as a 60's sunn and just want to verify that.  Anyone got any suggestions?
Thanks,
Andy

IIRC, the 312S came out in the early to mid seventies, along with the 612S and 610S. First I saw of it was in the 1974 catalog.

If it has any original speakers left you might check the frames for a manufacturing date.

I don't remember a 3-12 option with the 60s tube amps, but I could almost swear there was one when solid states were introduced around 69-70.  But my recollection is a lot fuzzy.
