Turn Table Decision

I bought my first TT in 1979 while a freshman in high school -.a Dual CS508 ULM, and I still have it, currently with an inexpensive Audio Technica cartridge, I was using it until very recently, when I received in a trade a Marantz 6200 with a Shure v15 type IV cartridge. The problem is the Marantz has a hum. Both channels, volume-dependent. I reconnected the Dual and there is no hum, so I am pretty sure it is the Marantz. I played around with my multimeter, and I cannot find anything obvious. 

So my question is: Do I spend $100-$200 (guessing) to fix the Marantz, or do I just stick with the Dual (or do I suck it up and buy a better TT)?

The rest of the system, if it helps: Acoustic Research AR3a speakers; Audio Research M100 tube monoblocks; JENA Labs interconnects; conrad-johnson PV12 tube preamp with phono stage; and a McIntosh MR67 tube tuner.

Thanks.

Shure cartridges have a ground tab on the right channel. If the tab is on the cartridge it should be removed. These are the instructions from the Shure website. Give it a shot!


CONNECTIONS (see Figure 1): R~ght "hot" lead (usually red) to "R," rlght ground (usually green) to RG " Left "hot" lead (usually white) to "L," left ground (usually blue) to "LG " If metal head IS causing ground loop hum, remove the ground tab The metallic cartrldge shleld is disconnected from the right channel ground by the removal of the ground tab

If you like the Marantz you should keep it . You should replace the stylus on that 40 year old Shure cartridge. LP gear sells a replacement!

BTW, since that table is over 40 years old a new belt might be in order!
