[Boatanchors] Filter cap question

[Brian Clarke]

Hello Ray,

 

Your response says nothing about the present quality of your replacement
caps, let along whether you've taken any notice of my warnings. As far as I
can discover, the FL-2000 series used switched-mode power supplies; but did
they use half-wave or full-wave rectification, and where in the circuit were
these 100 uF capacitors - just after the mains rectifier or after the
switching circuitry?

 

If you can't reform electrolytic capacitors, if you don't have a
current-limited HV power supply, if you won't check the balancing resistors,
if you won't check the other DC rails, I suggest for your own safety that
you take the power supply to a properly accredited repair person.

 

Regards, Brian

The caps I'm thinking of using come out of an FL 2000 amp that has been
parted out.
