    MR 80 station preset buttons don't always work

    Nice to see the MR80 is still alive, took me 20 years to get one, after repairing it got put in my main system. Finally got new glass for the 80, will pull it from the system and complete the rebuild, nice match to the C32, next is to get the MCD7008 working.

    McIntosh mc2300 becomes unstable at 120 volts

    First thing is to replace the electrolytic capacitors on the driver boards, the C1 - C2 330uF (use 470uF) can cause stability and turn on problems !!
