I run the AL-1500 blower at max speed. No problems after many
years of RTTY contests. I run 750 ma plate current on RTTY.

Can anyone tell me how much power an AL-1500 is rated to produce
at a 100% duty cycle?
During RTTY contests and outputting about 1000 watts, the tube
side of the cabinet gets mighty warm. The power supply side
seems cool - but then, that's with the cover on. I don't know
how hot is too hot and it would be useful to know at least how
much continuous power the supply is rated for.
Tube cooling is probably another issue...
