[Amps] Shunt resistors for a bridge made of 6A10 diodes in Alpha 91b

[TexasRF at aol.com]

These avalanche diodes require no shunt resistors or capacitors. Could not  
be easier than that!

G’day

I am refurbishing the power supply board in my Alpha  91b and am going to 
replace the KD202P diodes which make up the bridge with  6A10 diodes (1000V 
6A and only A$1.95 each). 

The original bridge had  strings of five KD202P a side, with shunt 
resistors across each diode of 500K  1W. The stud mounted diodes are looking pretty 
burnt around the retaining  washers/bolts, so it is definitely time (and I 
have a strange earth leakage  fault).

Please, I’d really appreciate some advice about what value of  shunt 
resistor to use on each of the twenty 6A10 that will make up the  bridge?

PS The replacement encapsulated bridge rectifier sold by  Alpha/RKR designs 
(5kV, 2A) is US$150, so this the reason for looking for a  cheaper solution.
