Hockey Puck SIT 2SK180 by Tokin source NOS

Tubes do have a wonderful appeal. I have a SET using EL34's that almost duplicates the SIT-2.
Power, distortion, damping are very similar. Bandwidth is wider on the SIT.

Carefully matched AB into a pair of OB Voxatives shows only small difference,
not enough to care about.

Of course that was largely the point of the SIT-2.

Mr. Pass i find France produced germanium triodes was in the 50's.

Tokin is much more powerful and have lot of gain if compare to Sony vfets.
On the other side have more input capacitance and distortion.
Just curious about THF-51S and 182E potential in amplification.
Quick switching = better sound ?
