[Heathkit] Hot Water 101 Final Question

[William Aycock]

Fellow Heathkittens,
I have a HW 101 and just replaced some bad 6146 finals with some 6146As 
from Sylvania.  With the 6146As, the plate current is all haywire.  When 
you place it in Tune, the plate current is about 90 milliamps with no 
drive.  Key the mike and the plate current pegs the needle. Has anyone 
experienced anything like this?  The only thing that I can think of is 
that the 6146A is not a direct replacement for the 6146 although the 
Heathkit manual for the HW 101 said that either may be used.

Help!!!! and Thanks,
Bill KC5MN
