Calling all SL-1200/1210 owners!

Anyway I wont be competing so much with things he does, my forte is power supply design. Though I will obviously play with other things. What I want to work on is that the power system is almost digital, it is a series of on and offs, and the more on and off the better as they use in lathe drive. I have ideas to simulate a greater number of poles in how the motor is driven. Also the motor needs very much lower impedance feed. There is still backlash in the motor.

If you want a quick peek inside my PS-1200 PSU just let me know ;)

But no direct copies, mind! :eyebrows:

The thing about the SL-1210 is its amazingly accurate speed stability and virtually non-existent W&F, which has a remarkable knock-on effect in various areas of its sonic performance. Most T/Ts these days (even very expensive ones) are just toys in comparison.

Nick,

Marco, yes lovely pieces aren't they. It was a bit of guesswork really, but luckily it works out fine for me. I'm not butted right up against the pivot, but pretty close.

You get away with it because of the extra mass on top of your 103 Pro.

I havent spun any vinyl for 7 weeks now, the chap building my pre has had family illness problems and is running a month late. I'm beginning to climb the walls. My Quad actives are much better now they run from dvd player rather than ipod, the same chap is going to mod these too in the near future, so I should have an excellent system by the summer.

Yeah no doubt, mate. I'm sorry to hear about the delay. Hopefully you'll also be able to take a trip up to sunny Wrexham :)

Not in the slightest bit interested in what is in your PSU. Amateur prat arounds are good fun but don't compete with the *master* :ner:

You will just have to accept you will have second best and live with it :smoking:

Your description is common knowledge and is really gobble de gook "amazingly accurate speed stability and virtually non-existent W&F" how are you measuring it, since whan has any test equipment told you anything sensible. Torque my man Torque, that is king in car engine design same in turntable motor design. Forget your bloody stupid BHP. In a T/T it is stopping and starting torque, so does that mean when you press the button, nah!!! it is happening everytime a pole passes the coil. The trouble with a direct drive is that it is *never* rotating at the right speed. It averages the right speed, but you don't necessarily notice it as it happens in a split second. BUT it effects how you percieve music. Guy was muttering about it in the version that Technics did for the cutting lathe. Needs much bigger motor with many more poles. I am playing at simulating that.

LOL. We'll compare T/Ts then when yours is finished ;)

I agree with you about torque. Measurements? Look at the 1210 spec in the manual!

My (very good) ears and my experience with a multitude of T/Ts, though, tell me all I need to know about the deck's performance.

And I won't ask you again, old chap, are you keeping the stock arm or is dementia addling the grey matter? :ner:

Why on earth would he want to?

It will stay as long as I want it to, it is the tt I am playing with. THEN well I might build my own if I have time :smoking:

So the stock arm is staying? - Excellent. Gosh you're hard work!

Actually, if you dispose of the rank-rotten stock internal wiring and phono cables and replace them with Cardas sliver linz and good quality phono interconnects, fit a decent counterweight balance and headshell, and add some silicon fluid damping, the Technics arm is very, very good :)

Build your own, by all means, and I'm sure it will be excellent, but don't automatically assume it will be better than the modified stock arm I've described above :smoking:

Also, fitting a decent mat is a must. The standard rubber thing is shit and does next to hee-haw (a rather quaint Scottish expression) to damp the ringing platter.

Mmm... I use to have a brand new Hadcock GH242 Integra. I sold it. Do you wonder why? ;)

The amazing thing about you is you *actually* think you are telling me something. Everyone knows now you are full of hot air and promises promises promises, your worse than an air hostess :lol::lol:

If my customers had to wait as long for products as you have strung out the panting hoards with your teasing bullsh1t about this, I would still be building last years orders.

<Snigger>

Well, Richy-boy, like I said, we'll compare T/Ts when yours is finished. I'm fascinated to see/hear what you come up with.

In the meantime I'm just making sure I keep you right ;)

Marco.
