Counterpoint SA 7.1 Preamp Tube

Technical Summary:
The
unit has two 12AX7 tubes in the phono stage and originally had two 12AY7's in
the line stage. Later versions used a two 6DJ8's in the line stage to overcome a
tendency of the older tube to "whistle." As with all Counterpoint preamps, there
are two gain stages in the phono section with passive riaa equalization. All
versions (12AY7 line stage, and the first versions of the 6DJ8 design) have a
gain stage followed by a cathode-follower. Later units have a MOSFET
source-follower after the 6DJ8 gain stage. There is no loop feedback Three
line-level inputs. There are single pairs of tape out and main out. Input
Selector, Tape monitor, Balance, Volume, Mute and Power controls. Aluminum front
panel finished in silver anodize
