A good starter unit indeed.... I'd like to start there! No additional info here, not beyond the sales lit!
It is the marantz tt-15s1. One ground goes underneath connected to chassis and then another that is part of the RCA's. Do i have something confused I am guessing haha
I'm having sylabance issues with a couple of RTI 180 gram remasters ("Graceland" and "Come Away With Me"). Is this typical of RTI or is something wrong with my cartridge alignment? I have a Rega RP3 with the Elys 2 cartridge factory installed.
Try disconnecting one of the two ground wires. Then the other. See if that helps.
The issue of PROPER grounding is always debatable - and it is very likely to be ALWAYS case to case different.
In my R&D turntable, I am using MANY separate ground wires, all coming together for the very first time at the
preamp chassis ground post. The ultimate capability of this TT is 5 (in words: five ) tonearms - and if the layout of the tonearms used would allow for 5 separate grounding wires, I would have certainly used them. As it is, one of the arms has ground shared with one channel of the RCA connector by design - and there is no way around it. That arm does NOT use wires for the electrical connection to the outside world - and there simply is no place for the additional fifth well of mercury for the separate ground connection.
The reason for separate grounding wires (and the ungainly mess it creates ) is, obviously, to first ground everything ( motor, bearing, subchassis, ANYTHING METAL or CONDUCTIVE ) - and secondly, even more important, not to create any ground loop(s).
You can use any ohm meter/multimeter to check for contuinity in the grounding. Best audio equipment has the possibility to BREAK ground connection if there is a ground loop someplace ( FM Acoustics first springs to mind, but there undoubtedly were and are others that will allow for that ). Ideally, each and every component in a "circuit" should be star grounded - that is to say, any ground returns connected to the same point. That is extremely difficult, if not physically impossible to do in a real system.
Do not be surprised to find that manufacturers have cut corners in this department, skimped on making a ground connection for say a motor shield in turntables, made their components compatible with their other components only, etc, etc, etc - it is the reality.
I simply adore, worship, etc, the Tesla NC470 / NAD 5120 / Lenco L800 turntable. Its Aichille's heel is grounding - could not possibly have been worse than it was/is, the thing buzzes as hornet's nest. As it is, the only bearable combinations regarding hum/buzz are very low impedance cartridges with relatively high output voltage - anything run of the mill impedance wise will be objectionable, not to mention high impedance designs, which are unacceptable on this table. If and when the time will allow, I will modify this hornet's nest and document each and every step how to do it right. I will post it over on the vinyl engine forum, as this exceeds the scope of head-fi.
I have grown to accept zero tolerance for hum/buzz - ultimately, I want "white/pink" residual noise in any of my systems, with no hum audible as such. It is ( almost ) always doable - but never easy to achieve.
