The KAB PSU mods are an easy recommendation as are the Isonoe Sorbothane Boots from KAB. I’ve used the older switched mode PS units sporting the green light box to wonderful results.
For the platter bearing, EAR Isodamp SD-125PSA (same stuff used by SME) works well applied to the underside of the bearing thrust plate along with a few other tricks well documented in various threads.
An SL1200 can also work exceptionally well using aftermarket tonearms, especially considering use of most modern MC cartridges. Sound Supports in the UK has very affordable options for accurately mounting tonearms including the NLA Jelco original TK850S which I’ve used multiple times. Mogami W2549 based Straight DIN to RCA cables are also a great way to "cheat", especially wired with a optional external drain wire for NOT connecting the shielding to ground if your environment allows.
Record mats can also have a dramatic affect, just like peanut butter ;-) Any suitable machinist should be able to remove the raised edge lip on the platter’s face for complete freedom to experiment - also well documented in various threads. Just pay attention to not overload the original bearing/drive system with too much mass.
