that I must have a leak in the pad that raises to give G#. However, I cannot
see a leak using a leak light. My second thought is that the G key is not
open enough I did lever it up a little, but I am reluctant to do more

I had a similar problem on my B-flat Silva Bet that you played at my house
(and that reminds me, I never did get around to replacing the weak
spring...). The trouble was a leak, but not a pad leak. The ring stack was
a tad misaligned, so that it let some air in under the ring, even when it
felt to me as though my finger made a good seal. On an all-metal clarinet,
there's no temperature difference between the ring and the lip of the hole,
so it's easy not to feel a problem like that. If you ask your son to sit on
the floor and put a leak light up through the bell while you hold the
clarinet in playing position, he might see a sliver of light under that ring.

You've collected an impressive assortment of Neat Stuff. How nifty that you
found a Silva Bet in A! Good luck with it--

(thinking about how many repair projects I really intended to get around to,
any day now...)
