Frank, I will gather up some basic examples and we will test them as "extra" items in your chamber once its done if thats ok with you... I think it would be the sudden release of pressure as when the boat comes shallow that would be the most damaging. This would cause these items to not explode but perhaps rupture. Potting these small amplifier cards as an example would not prove that difficult should the need be there. (I will cross this bridge in time) As for myself, if I venture down beyond the level that natural light can penetrate, I've gone too far. Thanks for your insight as always.

Ambient subs generally don't go that deep, or stay down that long. It would require using mix gas and extra certifications etc. and still is very risky. I think most ambient subs are built that way to reduce cost and complexity ( and weight) so I can't see where a capacitor or other sealed electronic device would suffer much from 2 or 3 atmospheres. It might be a good use for the testing chamber to try a few small devices containing items like that and see if they still work. Frank D.
