[Collins] 516F-2 power supply tester

[Dr.Gerald Johnson]

It might be a good idea to load the heater winding. Its 60 watts can lower 
the high voltage from added primary winding drop. A poor connection in 
that winding could show good no load voltage (and a normal winding will 
show high voltage at no load) but not support the tubes properly. Its worth 
checking.
