Hi George...that comment really doesn`t apply as most Broadcast transmitters
are several miles away from their studios so blower noise in most situations
is not a factor. All the amps I have built and use have internal blowers
with good balance and chassis isolation and are relatively quiet..kind of
like using good engineering in origional design instead of a necessary add
on after the project is completed! I`m sure you also think of this in some
of your designs.
