Did altitude just blow out 2 MPS's?, Put the in my checked baggage...now won't hold vac. Options

[FlacaProductions]

Brought two of my 3 MPS back to L.A. from Indiana while I await the arrival of my LCR55A so that I could do some bench plotting and tuning only to find that neither one of the now holds any sort of a vacuum.

Both ran fine in the car before flight - just needed some adjustment. One has the factory plug replaced with a Tangerine model - the other is still factory sealed.

Did being in the unpressurized cargo area in my checked baggage blow them both?

That would really stink....

Considering that the ALPS and the Rockies were thought about in 1966-67 when Bosch was engineering that device, I would think that it would be good to 10,000 ft. AT LEAST. Add in the 100% German engineering user-error allotment and...........

If the cabin altitude was a little higher than that you would be offered oxygen.

I doubt the shock (Physical) would cause them to fail.

A sudden differential 10K to 2K cabin altitude in a minute or two may have an effect? (IMG:style_emoticons/default/confused24.gif)

This is an interesting issue - I would - if I were you - double check the test performed after the flight - perhaps it was an error within the experiment?

Good luck with this one - CTC
