SB-110a help

[Leisman]

Anyone on the list who might be able to help me with an SB-110 problem?
I have an SB-110a that operates very well, 95 watts output cw, but to
getbthe full 95 I have to turn the mic/cw control almost full clockwise,
which can't be normal.  I have checked the tube (6EA8) and it checks
good, and I've even exchanged it with one of the other 6EA8's, same
results.   The voltages around the tube and the resistances all check
normal.  I'm lost for ideas at this point. especially since this is the
first stage in the rig for modulating/ keying the transmitter.  Any
ideas on where to go next would be greatly appreciated.

Thanks,

Dave, W8QW
