Ok, thanks for the links. That's the sort of thing that's needed. To get started, if you have a DVM, follow this step in the adjustments. Do not attempt other adjustments in any way - ignore them.
Your pictures show that you know where the test points are. What you need to do is:
1) Put the probes on the test points shown (this from the 1st step in the Service Manual, sec 3).
2) Read the voltage shown on your DVM and report it here.
3) If it is not near the 14v called for use a small _plastic_ slotted tool to adjust RV101 for 14.0 volts. Note the original position of the little pot in case you need to return it to that position.
4) IF you cannot achieve 14 volts, turn off the AC power and then rotate the pot from end to end 4 or 5 times. Power the AC up again and try step 3 again. note the range of measured voltages - one for each end of the range and report them here.
5) IF you can achieve 14 volts, allow the turntable to sit for a few hours and watch how the voltage changes over that time. Don't try to run the TT - just let it idle. This tells you whether there is drift in the power supply voltage regulator or not.
6) If it remains stable, though, button the table up and see how it works.
If it continues to go !bang! with the tonearm, what happens with the platter? Does it spin up to really fast? That is, does it fall out of regulating the speed? What happens if you rock the 33/45 speed switches a few times? Clean those contacts if you can with DeOxit.
OK, that's enough for now. Report out what you discover. If all the steps above make your eyes roll back in your head, that's ok. Find someone local to help you. Advertise on Craigslist. I know there are a number of AK guys in the area. Otherwise, find an old record store and ask the guy who to take a turntable to.
Cheers,
David
