That's why you should add an Over-Voltage protection module to the power
supply.

Dudley,
I agree. Our club had an Astron RM-35 that had the series pass transistor
fail (short). The output voltage went to the maximum provided by the
transformer & the 2 rigs connected to it were damaged. The Yaesu FT-950 was
repairable, but a Yaesu FM rig was not economical to repair.
A problem with linear supplies is that if the series transistor fails, the
result is a serious over-voltage situation.

Keep am eye on the analog power supplies , over time they will begin to
lose voltage regulation and will need to be repaired or replaced.
