Hi, I understand that, but just a quick test with an ESR meter is no harm,
it might detect a completely bust cap. (i will have to order some new caps) I have just downloaded the diagram layout, since I can not read some of the values of the large black caps as the righting is faded away, the schematic does not show capacitor values, any idea on top of the schematic are colums S C R, What is this?
