Hi Terry

The 37-675 Standard also used a shadowmeter and Magnetic Tuning, but no automatic tuning mechanism.

There were some 1938 models that used a shadowmeter. None of these had Magnetic Tuning, though.

Yes, in those it is. In 20/90 it is a metal spring that holds the rotor in the cradles of the outer walls.morzh — 01:39 PM
