Remove the bolts, lift the headstack off the mahcine [there is a cover over the stack that will need to be removed first... just like it needs to be removed when you're doing an 'azimuth' alignment].
The stack should lift straight off. Do NOT force anything... and you should be fine. Then send the stack to JRF... you'll probably want to be seated when John tells you the price of new heads [if they are indeed shot... they may just need a lapping which, relatively speaking, is a pretty inexpensive proposition].
Best of luck with it.
here's the thing-
i bought the MTR MkII over a year ago. i was touring the whole time and just got a big console and fired up the otari.
i cleaned it and aligned it with a fresh MRL tape.
recorded few songs and it sounds pretty nice (about 10 times more musical than my DAW regardless of signal to noise and freq response...). however, there are some anormalities that needs a more experienced check up.
-channels that do not sound identical.
-different sound overall between the repro head and the sel/rep head.
-sqeeks while rewinding(maybe motor needs lubrication?) etc.
plus ive never had a different machine so i don't know what sonic/mechanical condition the machine is in general.
i need a more experinenced person to go through and determine what needs to be done.
im not experienced enough to tell.
