I'm recapping a Lafayette LT425T tuner . It has DS1P rectifier diodes (2). PS is -21vdc and mains fuse is 0.7A. I have a lot of 1n4004 diodes I would like to use . I had the tuner playing and it didn't draw anything near 1A . Can you use the mains fuse amp rating in choosing the diode's amperage rating ? (higher of course). NTE 116 for DS1P replacement .
