Shure phono preamp information request.

alaskanaudio · 28th August 2004, 09:14 PM

Back in the mid 1960’s Shure made a phono preamp that was meant for high quality commercial use. It used 2 dual triodes per channel and the last stage drove a UTC or other 600 ohm output line transformer. It also featured adjustable RIAA equalization and output levels. Does any one remember this preamp and perhaps have a diagram for it? I cannot remember the model number. It is not the common inexpensive M60, M61 or M65.
