TD160 Hum suggestions (Yes, another new post)

Posted by contrapuntal (A) on May 21, 2016 at 18:41:29

I know, there are a ton of posts on this already, however I have little idea what other "hums" actually sound like. And there are so many suggestions, it is a bit confusing to follow.

Just a plain TD160. Older AT cartridge but still looks fine under scope and otherwise sounds good.

Symptom: Has a hum, as usual, I tap the cartridge-I know, sounds bad and could be but it is a very lite touch and it takes the hum down 70%, but it is still there. Periodically, every hour or two of play, repeat.

How loud: at it's highest too loud to play an lp. At 9:00 volume with nothing playing it is too loud. When I tap it, I would have to turn the volume up rather higher to match the previous louder hum.

Tried and changed nothing: Disconnected-Lubed carefully cartridge connections. Moved power lines. inner connects etc. Tried two preamps, a cheap black face (kenwood?) and a Pioneer c-21 plus a MAC 4100 receiver. Hum does not change at all.

Tried and helped, but not 100%: Couple days ago after seeing another thread here, I tried to rearrange/separate the 4 wires at the connection to cart. from each other-- This helped tremendously. But no telling for how long.

But hum is still there, but not at 9:00. I have to turn up to 1:00 and then it is still not as prominent as it used to be at 9:00. I never turn past 11.5 when listening in my smaller room anyway.

Must be something in wires or cart, and I think from playing with the it that the sound I am hearing is motor induced, (a slight sound change from 33 to Off.) It almost sounds like tube induced hum, but I use SS.

So can I rid this table of this hum for good? Even the now slight hum?

Thanks----
