You are correct, my oops. I was thinking peak voltage on the plate and you were
talking RMS.

However, your example of 600 VRMS on the plate of a 6146 grossly exceeds the
manufacturer's ratings. RCA rates the 6146 at 400 VDC absolute max, which
corresponds to a RMS max of about 280 V when properly tuned. I realize your
example was just for discussion but we might as well discuss real world. :-)
