[Amps] Drake L7 in need of TLC? Advice please!

**  replacing all of the diodes with the same type number is good 
engineering practice.

**  200 - 500 uF. 450v units should be ok.

**  Equalizing resistors are not good engineering practice.

**  No, but a step-start would be a circuit improvement.

>I have read about replacing the 0.82 ohm fuse resistor with a 10 ñ 15

**  A resistor that will limit fault-I to <200A and not come apart in the 
process..
