What happens is that when the tonearm is at rest, one screw is positioned under that hole, however when you move the tonearm onto the platter (as per instructions), it moves a different screw under that hole - hence two different adjustments. Something confusing is that there are two adjustments performed through the same hole (under a rubber cap near where the tonearm enters the table).You can get them from vinylengine with a free account, the QD33 one is here: There are a lot of adjustments that need to be done as per the service manual.If neither of them pop up you *should* address it, but if the inner one is poking up and the outer one is down, don't worry about it - all functions of the table will still work normally.

I think these either broke really easily or were like this from factory (it's just the outer one), either way, if there are problems with your turntable then this isn't it. They mistakenly think this might be a cause of a whole bunch of issues (as did I) - but actually - it's not a problem at all.

The second 'issue' most people notice is that the record size detection 'prongs' that poke out of the platter are amiss, and that only one of them is poking up.

This one *just* cleared when mounted upright.

I replaced the main PSU capacitor (2200uF axial) with a slightly higher value 2700uF Panasonic FM radial, you can do whatever you want here - just make sure it physically fits.

This will generally restore all electronic function, particularly the platter and tonearm either completely not working or only working intermittently. Generally the Panasonic/Matsushita (triangle logo) are fine. Check all boards (function button board, power supply board, motor board).

I took the opportunity to replace them all, but if you are on a budget, I'd recommend replacing all the TK branded ones at least. The particular ones that were bad were ALL the 47uF ones in my unit, down to 10uF or worse in some cases.

The first major problem is that Technics cheaped out and used Toshin Kogyo capacitors in these (they say TK on them).

It's just a budget table but apparently decent enough. These points will likely apply to similar Technics turntables like the SL-QD22, SL-BD33, SL-BD20, etc, not just the SL-QD33. I had some time this morning to finish it off and thought I'd share, in case someone does a search in the future. Many threads ended with no conclusion, so I suspect many tables were binned. I had to repair one of these recently, and while searching for answers, there were ~20 threads of people wondering why the platter stopped spinning / tonearm stopped moving, or things would work intermittently.
