[AMRadio] WTB SB-220

[Patrick Jankowiak]

I have found that a good rule of thumb for using linear 
amplifiers on AM without burning up the tubes is the max. carrier 
output from the linear should be no more than half the total CCS 
dissipaton of the tubes. Case in point the pair of 6146's at 
20-25W carrier, etc.

I run my National NCL-2000 at carrier 100W output, and dissipate 
300W at carrier, in a pair of 8122's. Last a loooong time..
