"The eico 81 has a 12au7 in front of the 12ax7 driver/splitter tube, and the au7 is for the tape monitor circuit."
Buffering the recording O/Ps with cathode followers is a good thing. Loading down the low level mag. preamp section will result in info. loss.
"I wonder if including that tube would be too much gain if i also used it my amp?"
Excessive gain is a serious negative. Attenuating a signal only to boost in again has a very deleterious effect on S/N ratio. :>((
As I stated previously, I'd like to see a photo of the chassis being worked on.
