Don, you can probably still find those pin to 1/2" cap adapters
somewhere.  If it were me, I'd just change the thing to whatever you
need.  250TH/L's are still pretty plentiful so you probably wouldn't
go wrong there.  Does the xmtr have a neutralizing cap and circuit in
place?  Another alternative would be a 304TL, but I've heard they can
be hard to neutralize or something, never used one myself.  806's are
hard to find, and you'd sure be no better off than just using a 250TH.
