[WriteLog] Collins 30L-1 on RTTY

[Radio Steve]

Hi All...
I have a new 30L-1 I plan to use for occasional use on RTTY, no contests. Just setting up an old Collins station for fun.  Mostly will use on SSB. Howevr, When I want to make some RTTY contacts...how much power "output" can I safley get out of the 30L-1 without damge. It has 811A's in it now, but I plan on using 572B for finals, therefore not hurting the tubes as far as Plate Dissapation on RTTY...but worroy about the Power Supply being small and made for SSB. You guys think I can get 300 Watts output with the 572B's and a LARGE muffin fan sucking cool air around the Plate Xfmr  ?
Thanks in advance... Steve WB2VZV
