He thinks the platter is ok. If it’s the spindle, is there a way to adjust it?

For a direct drive, it’s probably not user serviceable as the spindle is directly connected to the motor. The motor itself may be askew. At that point, I’d be looking to either send it into KAB Electronics for repair or to seek a replacement. Before doing either, I’d consult a service manual on Vinyl Engine.

The Hana SH is a great gateway into MC carts if you have a phono like the Cambridge Duo. The Duo has good MM input quals for its price point and the SH can leverage that input. The SH Mk 1 models are still available at reduced cost. The SAE 1000LT is an even better deal if you can find one.
If you think a more advanced MC phono or a SUT is in your future, you can use the Hana SL on the Duo MC input as a starter. However, I don’t think that combo would be as good as the SH with Duo for the longer term.
Edit: A quick check suggests that the MM input on the Hegel is at least as good as that of the Cambridge Duo. Same SH recommendation applies.

Given the age, I would also check to see if the plinth is straight. It looks like that might be an MDF plinth, which will undoubtedly corrode over time. Especially if it's been exposed to humidity or temperature changes.
If that's the case, it's likely more trouble than it's worth to fix it.

Welp....the table came on the 27th (SL100C)....easy to set up and ran it last night, sounded great (with my cartridge on it). Very happy stepping up from a lower end but capable AT table...and if this is the sound i get fomr htis table, will be happy for a good bit of time.
But......today was setting up a lokius for it, or going to and for some reason wanted to see how quiet it was with nothing playing. Got to 55 and there it was, a hum...static like. Faint, but there, louder as the volume got to 65+. That hum was not there on the AT table nor on anything else. Know the pine tree cables i have are fine, just the same i tried the stock, no difference. Thinking an internal grounding issue?...as when i had the head shell off there was an good increase of hum seemingly emanating from the tonearm, could kind of change it a bit touching the arm....interesting....so contacted Technics support....lets see how long this "ticket" takes.
I just got the lokius back as it was new, also out of the box, and had a bad pair of switches on it....Grrrrrrrrr

i actually have two, or will have....one between the CD player and the amp, and bought another one to be between the turntable and the amp. I do use the one i have on the CD player a good bit as too many CD's just need a tweaking...not much of an adjustment, but some. So wanted one for the table as occasionally (more so with newer and metal releases) there just needs to be some adjustment. Still amazed at how many new releases sound like crap and so many of the older sound so good. What the hell do these folks listen to that says...yeah, this sounds good, release it....i stray....
I really wanted just one, but no loop on the Hegal and while i looked at a switch box (balance to non - Pine Tree makes one) this was just the cleaner way to go and did not cost much more than getting the switch. They really work great for tweaking, especially for the cost.
I had yet to hook it to the new table as was waiting for the repair on that unit to get back to me....now i wait more, lol.

with phones on (which is most of my listening right now)....about 47-52....not audible, but should not hum. If my $300.00 AT table did not hum....I am betting this one shouldn't.
Speakers, with the Hegel, no idea as i really do not so much there...betting about the same, maybe a tad more at times.

Ground loops can sometimes form if there is a powered device between the phono preamp and the input of the integrated amp. If you suspect you have a ground loop, first make sure all of the powered devices (phono pre, lokius, and integrated amp) are all connected to the same power strip or conditioner. Ground loops can be fiendish to resolve sometimes.

The table is connected directly to the amp (table does not have a preamp).... it is using the amps mm phono stage.
Nothing has changed but the table.
The Lokius is not connected yet.

ok...i am going to need some help....not exactly the right topic but still part of the problem.
Put the AT table back on, kind of the same issue...though no extreme hum without a head shell on.
Found the hum coming from the connection of the left line cable into the MM phono stage of the Hegel amp.
No hum with just the right line hooked up.
Crackle in the hum gets lower when i take off the ground.
Happens even if wires not connect to a device.
So now, can not tell if the new table is having an issue till i find out what the bloody hell is going on here.
Can the on board phono amp be bad?...
I can start a thread if better to do so.

yes...the table ground is attached to the amp ground.
the odd thing is as soon as i plug a cable into the left line, just a loose cable, it starts....not so in the right.
also, never noticed this but when all is hooked up and i touch the cable from the table to the amp you can here me moving it...i create sound....amplified rubbing....no matter the cable grade, i am not sure i have ever had that happen.
This is driving me nutz

Yeah I’ve had ground loop hum before on a few occasions and it’s a bastard. I’ve had to almost strip out all connections one by one and then reinstate the them individually to see where it’s coming for and it’s been down to ground wires and cable and all sorts.
Have a google about how to solve hum, there are some really good guides out there that should help you.
And good luck!

Yup...yup yup yup......guess i know what i am doing this weekend....tearing it all apart and putting it all back, bit by bit by bit......weeeeeeeeeee
Guess i will take the amp for a walk first because if i can recreate that hum on the dining room table with just a turntable....that will eliminate everything else i suppose.....and if not, lol....

Yes...mine and theirs...same results.
Have pulled the amp out of the rack.
put in dining room, plugged in - still just putting a cable into the left RCA in produces a hum and not sure if that is normal.
but when i hook up either table and ground (in dining room, same outlet), hum is gone.....so something going on between what is on the rack, maybe the WattBox?...or strip?....later or tomorrow.
Of note, is my table supposed to make a low hum (have to be 70+ on vol.) and crackle with the head shell off?...as both still do that, even in the dining room hook up. I would have thought the arm without a head shell is a closed circuit.
