Hi, New to the forum.
Have had some Mcintosh stuff hoarded away for a while.
MA 5100 pre amp amp, MC 2505 power amp, Mac 1700 receiver,plus my 1972 pioneer sx 1500 td receiver.
Can I meld them together as a unit depending on receiver? There is a pre - main switch on the pioneer but not on the Mac.
Thanks,(I hope).
