W5M Power Xfrmr Question

[Bob Burns]

Hi John
 
I do not know the amplifier in question but I would first try running the  
transformer with no load at all and see what happens.  If it gets warm then  you 
know the answer. If not then I would try running it with one secondary  on 
load at a time to track down the problem. Check the diodes and electrolytics  at 
the same time.
 
I have had two transformers from Heath SB-line units (401 and 610) fail on  
me out of the fourteen or so in my various units and I think that is pretty 
good  considering the age of them all. Getting them rewound in the UK is an 
altogether  different issue though - have not solved that one yet.
