[Boatanchors] 51J PTO

[bavarianradio at comcast.net]

Hello all,
  I am in the process of  working on a Collins 51J(2?) that I have owned for about 20 years. It has a 70E-7A PTO  that had been monkeyed with before I got it and in a moment of impulse I tried to get it working and made it worse.(probably more than 10 years ago). I recently acquired a 70E-15 PTO also from a 51J2,I am assuming a later production run,  and I'm  wondering if I can use it in place of the 70E-7A. I looked on the PTO page and it seems to be the same except it uses a lower B+.  Any thoughts?? Many Thanks!! Ross W1EKG
