RR.  Another problem is the bleeder resistors produce too much heat for 
the electrolytics.  Changing from 25-kohmequalizers to c. 100kohm would

I still get full suds from an Amperex bottle that was made in 1967.  
Chinese tubes are currently good.  Triton [was Eimac] tubes reportedly 
have weak (but beautiful)*  anode-cooler spotwelds that fail with normal 
heating/cooling cycles.  Eimac tubes made in Salt Lake had the same 
problem - while those made in San Bruno did not.    
* Note - beautiful looking spotwelds are like unto beautiful women.
