With some perseverance this afternoon, I found the replacement thermo-switch
source for the PA-70V. Anyone wishing to thermally protect their amplifier
may want to consider using these switches.
In the case of the PA-70V, H.V. and R.F. isolation is achieved with a
one-inch glazed ceramic standoff that's attached to an angled,
anodized-aluminum bracket. The bracket is then attached to the 3CV1500A7's
anode with the same stainless-steel Aeroseal clamp that also holds the H.V.
strap. The thermostatic switch is then lightly cemented to the other end of
the porcelain standoff with most any heat-resistant cementing compound.
The thermostatic switches are offered in a wide range of temperature ratings
and mounting styles.
