What I weigh is how much money is saved, and what it might cost
if all the amplifiers have to be refitted with another brand or type of
tube.
Then, added to that, how much headache will be caused when
people do something wrong, and how likely they are to do that.
It's all a matter of time and money, no matter how you candy-coat
it.
