[Collins] 32S-3 final neutralization question ??

[pmills7 at houston.rr.com]

I am working on a RE 32S-3 and need to replace the finals.  Currently there 
is
one 6146B and one 6146A installed which obviously is not good.  Is there any
way to determine if this unit has the proper neutralization components 
installed to support the -B tubes?

thanks, 73,
