I was discussing the problem of voltage rise at turn-on or during 
standby operation if the 26Z5s are replaced with SS diodes.  The 
12BW4 is no different from the 26Z5 in this regard, so in this 
context it is not another option -- it is the same option.

Note that some people have reported clearance problems using 12BW4s, 
which are about 1/2" taller than 26Z5s.

Best regards,

Charles
