I do not agree at all on this issue, Carl, so I'm gonna try to tell you 
 A '4by15' (8281) works best with an anode-v supply of 10k.  IMO, 14k piv 
rated rectifier strings WOULD be needed.  However,  the 8281's anode-I 
current requirement of 6A would be somewhat easier to meet with 1N5408s 
in a FWB rectifier configuration.  Using microwave-oven rectifier blocks, 
one would probably need at least 4 in parallel per FWB leg to reliably 
deliver 6A.  The cost of (16) $15 rectifier blocks is $240.  My cost for 
(56) 1N5408's is $6.16.
