Valve Power Transformer testing (my sanity)

[makinrose]

What I think is missing here is why we are suspicious of the power transformer in the first place?  What is it doing?  Are you blowing fuses?  Do you have the correct voltages??   As Kevin mentioned this should be done with a limiter.  A meter can help you determine if the transformer is grossly bad. 

GeoFX has a good run down of simple power transformer test you can perform here: Power Transformer (geofex.com)
