Sony TA-3200F
(1970 - 1976)

True bestseller!
The TA-3200F is a revised version of the late 60s TA-3120F - the latter being based on the 1/3-width TA-3120A.
The crisp and tight 3200F found its way into many a rig, multi-amped or not. The test position of the "normal/test" back switch allows to extend response to full-DC while the "normal" position cuts the first few Hz.

This DC, OCL, SEPP OTL power amp was made to complement the TA-2000F preamp (shown below), just like the original TA-3120 and TA-3120A were tailored for the original TA-2000 and just like the STR-6200 receiver was the FET version of the STR-6120.

The "smooth knobs" version seen here was Japan-only.
