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.
