-100V isnt even close to a full cutoff description since typical operating
bias in Class C is -90V for 250B's.

Back then, you keyed the cutoff bias of the amp.
My Central Electronics 20A had -100 vdc out the back that followed the
keying and did a full cutoff
of the HB 4X250's with operating bias set for class C.
No clicks....

I don't think this is true. Class C will generate terrible key clicks
because it won't preserve the keying envelope.

In CW it can run Class C, but for SSB it has to be linear. 73 - Mike
