So in other words it’s a lot like most eighties Marantz stuff
The 6300 is a solid CEC built table for its time, though it has had its fair share of known issues below:
1. The feet do not isolate rumble and vibration very well, so you'll need a solid surface and some dampening materials or different feet in able for the table to perform flawlessly.
2. Tonearm is somewhat heavy; the bayonet connector adds considerable weight to the tonearm making cartridge mating/selection tricky.
3. Tonearm gimbal bearings have been known to have some play in them that can add to noise and vibration issues compromising audio fidelity/quality.
4. Micro-switches located under the control panel can develop intermittent issues over time.
5. Stock RCA cables are of poor quality; they work but can be significantly improved with high quality replacements.
6. Stock tonearm wire is average quality, but can be greatly improved with Cardas Litz OFC 33awg.
7. Stock headshells are somewhat heavy and often have mis-aligned guide pins adding to inner groove distortion and tracking issues.
8. Stock potentiometers located on the bottom of 18VDC motor develop intermittent issues and cause speed drift, as well as, the control panel potentiometers too. DeOxit fader lube is a must have on these.
9. Stock Neon bulb for the AC driven strobe circuit can develop intermittent issues from time to time. Replacements are smaller and put out less light. I have yet to find a suitable replacement that looks and functions like the original OEM.
10. Stock platter mat is somewhat thin, cool looking, but not great for dampening and isolating out noise.
To be fair, the 6300 is over forty years old. It's definitely one of the best looking tables from the 70's, and with some added upgrades it becomes significantly better.
Make sure to have deoxit fader live handy and have a solid surface to try to iso it, the first high performance TT, much different from plastic stuff of later years I was referring to, I have a 2010 receiver I listen to day and night and I’m sure it would pair really nice for a small setup... how does it sound and what are you using it with? 2220-2270 would be a great vintage classic amp maybe also an early pioneer Yamaha or NAD
