[Amps] DIODE / RECTIFIER BLOCKS: SILEC: SPECS ?

["W.F van Wyk" <zs6arf@telkomsa.net>]

Need help with Diode/Rectifier blocks made by SILEC.

There is two type of markings: SILEC F 80 H and in small letter 7509 also SILEC 
F80 H and in small letters 7511.

What will be the voltage and amperage rating on these. They come out of a 
marine amp that has four 4cx250 tubes and power transformer 3000 volts. 

Any help will be greatly appreciated.
