Smaller sibling of the excellent TA-F80 but not the smallest : the TA-F50 was but it wasn't exported.
Inside is about the same, but smaller :
20Khz PPS power-supply (like that of a TA-F5), 12-fins Heat-pipe (that of the F80 has 21 fins), LEC transistors for the phono stage and two pairs of high fT bipolar output transistors.
Also, we're at Sony so even the small amplifier has that : a phono MC stage.
Gone were the quality ALPS 4-gang pots, the capacitance/resistance phono settings and the proximity of the i/os with the front plate / preamp section.
Kept however was the all-aluminium front and knobs.
Simple, reliable, powerful.
A small nudie here.
A real F60 here or here.
