[Amps] Astrons catching on Fire

Astrons catching Fire!?

Dear Mike and the Group,

What information can you offer on Astron power supplies
catching on fire?

Is there a suggested remedy to forestall or prevent such
catastrophe?

This is a Safety and Health related issue and deserves
the utmost consideration.

Thanks,

The Astrons use very marginal  filter caps. Add to that the component
laden pc boards mounted directly to the screw terminals and you are tempting
fate.

But the Astron RS-50 that I had produced quite a bit of acrid smoke when the
pc board caught fire. The RS-70 did the same thing but I was wise to the
smell
and shut it down before ignition.
