The Denon DP-62L was manufactured back in or around 1982. That makes the turntable 36 years old and I guarantee those electrolytic caps are out of spec. If you want a reliable turntable, without any issues, you want to totally recap the turntable.
Forget any half efforts or looking for caps that measure terribly, replace them all. What it costs to get into the turntable's electronics and replace any component argues that once you have someone in there, just go ahead and replace them all.
My DP-62L, which is currently in storage, was well kept but started to have trouble with the Lock light flickering on/off. It was the caps being out of spec that were the culprit and I could have tried to identify which cap caused the problem. I thought that was pretty stupid since once one cap goes bad that means others are bound to be bad or going to be bad soon.
Once in there, I replaced them all and had no further problems with anything in the turntable. I also had the main bearing replaced with a jewel/ceramic main bearing. The original main bearing made a thumping noise at 33RPM and that was caused by a worn thrust plate, ball and metal parts. Whoever does you main bearing, please make sure they have the ability to check out all parts of the bearing. They also should resurface all metal parts of the bearing if you want it to be the best it can be.
The main bearing is more than just the ball and thrust plate. Once those begin to wear, it is likely that the metal parts of the bearing have also worn. Replacing just the ball and/or thrust plate alone asks for early part failure. It may not happen but if you want to have a turntable for 20 years, these are the things you need to do to ensure it is like new.
My 62L is much better than a stock table but it costs money and time. If you really like the turntable, you should at least consider these steps.
