The GSB-201 only uses 20uf.  The capacitors are in series so the capacitance is 
divided by 5.  The replacement choke is good.  Throw the choke away.  With a 
capacitor input, you will have 1.4 x the transformer value.  So you will have 
the same value as the other amplifier.  But, one thing you will need higher 
tuning capacitor voltage to stand the voltage increase.  

So, you would want a transformer about 1250 volts x 1.414.  That will give you 
the same voltage as a choke input.  To make up for the choke, you will have to 
use bigger filter caps.  

Maybe you should read a little more about capacitor input power supplies before 
buying one.
