RE: re.watchdog and beyond



If the dreaded black spots are near to any soldered joint (this includes the
edge of the bell, which contains a soldered-in reinforcing wire), this is
caused by flux from the soldering operation "weeping" out over time (beneath
the lacquer).  I know that manufacturers do go to some length to "flush out
the flux" but clearly not far enough!

On another gripe, can anyone tell me which page of Encyclopaedia Britannica
describes how to replace the spring on cornet third valve triggers?  I held
a street party the last time I succeeded.  Now I just keep replacing the
elastic bands!  At Wigan Jazz Festival this year I was reassured to see that
Dennis Noday - a world-class jazz trumpeter - uses exactly the same
low-tech. solution.
