is a bit more narrow. I seem to have spent a lot of time demonstrating
that. Keeping the baseplate below 40C (and above 10) does indeed extend
their lifespan.

Cheers Bob.

I have a 2U 19" HP case that was used for a test set for a VNA. I will see
what the temperature is with that.

But the first thing is to test if they work.
