Technics 1210 internal regulation mods

[Paul Hynes]

Hi Mike,

I’m ok with a handshake on meeting but draw the line at holding someone’s hand while they quiver and quake for whatever reason.

I like to be tidy with my upgrades and removing all redundant components keeps things tidy. If anyone wants to do this a different way, that’s fine, as long as you do not leave anything on board that will cause problems.

Good advice regarding the coils.

Regards
Paul

I would suggest that anyone contemplating a bearing upgrade on the SL1200/1210 should do this before fitting my internal regulator upgrade. This will avoid disturbing the solid core copper or silver wire, used to connect the regulators to the motor board, when removing the motor board for bearing installation.

I upgraded a customer’s SL1210 last week and this already had a Mike New bearing fitted. I have to say that I am very impressed with this bearing. The bearing is so precise yet it runs so feely. Absolutely amazing. A first class product. I am looking forward to receiving my bearing from Mike.

Marco, if you're reading this, I hope you will appreciate WHY I did not want to install your MN base plate as you will appreciate that everything has to be taken out first and I knew there was a potential prob of possible damage to your PH PSU + regs My abilities are with mechanical rather than higher electronics of the nature that Paul, Martin and Anthony find commonplace and easy. Hope you understand mate.

Cheers

This will still leave C3 connected across the new supply.

If you look at the photo of my mod work you should just be able to see that I have left C3 in place (top, slightly left of centre).

The bearing is a truly great upgrade.

The bearing is a truly great upgrade.

And Jostein its even BETTER with Mike New's base plate, so don't forget folks to do these jobs FIRST before the PH PSU + regs!!!!

One question: Whats your Furutech Monza LP stabilzer like compared to others you have possibly used and whats the weight? I've tried really heavy buggers but they squash the life out of the music.

Cheers mate

You've left C3 and R2 and R4 (according to your picture) ( Any ideas why mate??


Do you always leave the plastic cover off the top of the motor coil as well?? Surely dust can get in there??

R2 and R4 perform no function with Q1 gone. C3 helps provide a little more regulation to the 21V line for the motor drive circuit.

Yes, I leave the plastic cover off because it sounds better. I did that ever since installing the MN bearing.

Thanks, I will check more on that base plate as well. I have only tried the Furutech Monza on this deck and it works great for me. The weight is 340 g. and has electrical damping through the piezo materials, as well as the mechanical damping.
