    Mica insulator placement

    I have a MA6100 I've been working on. I just pulled all 6 of the driver transistor to test them. Found 2 leaky. Anyway, in the process I did not notice 4 small round mica insulators under the transistors and they fell out. Can anyone please tell me which transistors the insulators go under? Al

    Oil/Grease option for smooth rotating bass/treble stick

    The MA6100 has a speaker balance feature on the same bass stick (same for trebel), so as to apply the bass more or less on one speaker vs other. The design of the stick is such that there are two concentric sticks one inside the other which allows to rotate the balance or bass independent of...

    Hello, I am looking for a MA6100 service manual. The version I have is last of production (1975-1979 and has the resistor instead of the zener diode on the phase inverter board. There is no serial on this unit and all the service manuals I can find online are a different version. Thanks

    MA 6100 Volume Issue

    Hello and Happy Thanksgiving! My dads McIntosh MA6100 is having issues with the volume control- it is only outputting high volume, (won't go lower or higher) and in certain devices there is a delay in shutting off. Is this something I can repair on my own, or recommended to send for service? Thanks!
