811/812 CCS phone dis is 27 watts with 82 watts output.
811/812 ICAS phone dis is 40 watts, with 120 watts output
811A/812A CCS Phone dis is 30 watts, with 85 watts output
811A/812A ICAS Phone dis is 45 watts, with 130 watts output.
Per RCA Transmitting tube manuals..Sadly, page 21 is missing from my Taylor
Taylor did not use ICAS Ratings to my knowledge.
RCA introduced those with the 1941 Tube Guides..
The 1939 ARRL handbook, page 80 shows the phone ratings for the T-55 as
1500 volts and 150 plate mills.Peak power output of 652 watts and a carrier
power of 168 watts..With the input of 225 watts and a output of 168 watts,
then the CCS Phone dissapation would have been 57 watts. Mike
