[Heathkit] 6146Bs

[pulsarxp at embarqmail.com]

Anyone wanting to sell me all their new 6146B tubes cheap, send them my way! 
I have replaced way too many regular 6146 tubes with B tubes in Heathkit, 
Collins, Drake, Johnson, etc.,  with never a problem.  NEVER !!!  As far as 
I am concerned this is a non issue.  As I said in many past posts, try them 
and see who is right.  Put them in and see if you have a problem.  (Yes 
Collins had a problem but it was because the neutralization cap was too 
marginal to begin with even with A type tubes and made a change to a beefier 
cap about the time they started using B tubes in the S-line).

As for RCA retracting their statement  they are interchangeable,  I 
challenge anyone to show me this retraction!  I want to see it.  Show it to 
me.  Put that retraction on this reflector.  (If you look at the tube 
parameters of the different variants, the differences are so slight, 
production runs could account for these slight differences).  It is true the 
Bs can put out more power but you need to increase the screen voltage to 
make them put out the extra power.
