SA-7 Preamplifier. This preamplifier was introduced in 1984 as the SA-7 as a lower-cost preamplifier. It was updated to "point one" status with the addition of an auto-mute feature in 1986. It features all-tube phono and line stages. As manufactured, has sufficient gain for MC cartridges but signal-to-noise not really good enough for MC use.

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 black or silver anodize. Discontinued middle of 1989. Original Retail Price: $495. Shipping weight* 19 lbs.
