//  Dick Errorhorn used Centralab coupling/bypassing service capacitors 
as C-tune and C-load tank padders.  He also used carbon-comp resistors 
that were rated at 350V max as equalizer resistors on 450V electrolytics. 
 

>Denny Had thought otherwise for years.

Denny Had sent Eimac the prototype for the MLA2500 for evaluation.  Two 
Eimac engineers recommended numerous changes.  Mr. Had made none of 
Eimac's recommended changes prior to going into production.  

>Eimac still honored their warranty, 

Eimac honors their warranty even in  cases of gold sputtering.  

>and the FCC did not seem to care.

FCC specs can be met without a tuned input.

cheers, Phil
