I put two on the power supply too.

While I don't use my L4 on AM, I do use it for contesting. I use two
muffin fans sitting on the top of the cabinet, one directly over each
tube. These are the lower speed fans so they are fairly quiet but they
still do a great job of providing additional cooling. They are
positioned to blow the warm air up.

At one time, there seemed to be great interest in the L-4B because it
could run 1 kw input on CW, RTTY, and AM. A lot of other amps were
rated at, for example 1,500 watts input on SSB but maybe only 700 or so
on AM because they didn't have power supplies, cooling, etc. for
continuous duty or high duty cycle modes. I'm sure there are some
users out there, maybe on some of the AM nets, that have direct
experience. Note, however, the top of the cabinet, especially over the
tubes, gets quite warm in such applications...

I too would be interested in the L4B's performance/use on AM. I may
use the DX-60 or T4XC as the driver, but same question, hi.
