COMMENT ON USE OF WOOD IN TC'S

    I've found it a good idea to dry the wood in 
the oven (before final finishing to size, to take 
care of warpage as it dries and shrinks) at 250° 
for a few hours and then, after finishing, coat 
it with a couple of layers of shellac (I happen 
to prefer orange because that's what a lot of the 
old timers did) or Urethane varnish.  I've never 
had any HV problems (at primary circuit voltages of course).
