[R-390] Re 26Z5 replacement

[pete williams]

 1.  Thanks to those who referred me to suppliers of  roll pins -- One
kind  soul says he can  help.

2, Not having to  do it  yet, but if  one decides to use  tubes in
lieu of 26Z5's  or Si diodes, is their any reason why 6BW4's could NOT
be used instead of the  12 BW4 as outlined in a recent post.

Reason for  suggesting is that the 12BW4 seems to be  non existent  at
this  time - 6BW4 still available . The power xfmr has a 12 V tap
unused at terminal #9. Rewiring to put the  fils in series  may not
cause   a load problem especially if  ovens  not  used. The  seriesed
fil  current would be 0.9  amp .
Any prohibitions ?
 Cheers
 Pete
