Black wire running to the point 0v marked with red arrow

I try to keep myself mainly involved with digital audio modification these days, but as a rare treat to all you 1200 owners I'll let you have a free but valuable piece of modification info .

The screw and earthing clip that Leo has marked out in the red text should be degreased with something like surgical alcohol. Those two bits should not be touched with your bare fingers if possible after that. Use a clean set of surgical gloves or a piece of kitchen tissue.
If you wish to go a bit further, you can even add a very thin layer of solder over the one side of the clip where it touches the bottom end of the screw.

Please don't ask what this mod does, since I won't give that part of my secret mod away . But yiu can make a before and after listening test and let me know if it worked for you .

This is turning into the Techie KliniK but seriously Stan ' that seems to make sense to me as the circuit board and everything on it must be very sensitive .

Great idea, I use isopropyl alcohol ( also known as IPA) for degreasing before soldering connections etc.

or to be really geeky, Caig Deoxit to clean contacts.

And as Stan says, wear gloves, dont touch contact areas with bare skin as you contaminate the surface with grease from your skin.

Hi Mark, I reckon we'll have quite a few 1200 owners rushing to do this mod, and 'professionals' who charge for their service quickly updating their websites to add this on their list of money making options .

[Mark Grant]

I dont have a Techie here so I am only commenting based on looking at the pictures

I always clean any metal to metal electrical contact and I guess you do too

Every little helps as they say..

Would the tonearm earthwire work better on that earth point as opposed to the screw on the pitch slider ( always doubted this is a good earth )
I have always had a background hum with my turntable but that could be part of the course using a tube pre amp i dont know.

Go easy guys, this thread is getting neurotic enough as it is

[chris@panteg]

Well iv'e just done mine , moved the earth tag without touching it and cleaned both contacts with isopropanol

So my earth is now in the correct place , Will listen at the weekend if i get a chance , not listened to my deck over crimbo ,too damn ill .

not listened to my deck over crimbo ,too damn ill .

Sorry to hear that, Chris. There are a lot of viruses going around and I was coughing and spluttering too. Damned hard to shake off, actually.
