I will test it later ,last time crown service this amp for a loud popping sound and p went black,but I did notice when I release the board I found a hex bolt under the board that crown must have lost and not remove that could have grounded on somethingCertainly looks as if it heated at some time, lift off a secondary feed component, IOW open up the secondary circuit and see if it still gets warm/hot if maybe the transformer rather than the load.
Max.
It looks more or less normal to me.Took these pictures of transformer and back of the board from my crown ce4000 amp ,after haVing a fault light.
No it does not. It looks like aging and improper flux removal.Took these pictures of transformer and back of the board from my crown ce4000 amp ,after haVing a fault light.
Right now I only have a multimeter and about to purchase a Tektronix TDS360 to used on the board1. Have you tested anything?
2. What test equipment do yo have on hand?
If you have the schematic - check isolation between any secondaries indicated as separate - shorted turns can include another winding if its bad enough.Right now I only have a multimeter and about to purchase a Tektronix TDS360 to used on the board
