first of all, GC is not the place to do that because we dont do any repairs.
you can drop the power by 50 or 100 watts if you like by pulling pairs
of tubes. inner, middle or outer pairs. even pulling 2 pairs of tubes to
drop the wattage down to 50 really wont drop the over all volume that
much, but it will change the sound a LOT. also, for every pair of tubes
you pull, also pull one recitifier tube.
