I am just curious if you can replinth sl1200 like you can with the sp10's.  I heard a few sp10s with massive custom wooden plinths that sounded good at RMAF.

I suspect you could somehow...but the SL-1200 has a pretty inert, and unique, tri-ply construction now.

The SP-10's were quasi-consumer offerings of broadcast decks (replacing Garrard 301/401 and the like) that wer made to be situated in large wood cabinets (that effectively provided the damping)

If you can imagine...the top and bottom pieces on the SL-1200 are some kind of dense rubber material....and the middle section if a very dense plastic.  It's sorta' constrained layer damping I suspect 

It works very well in damping out resonance/feedback, etc.....but, is perhaps too effective in some ways.  When you change out the plastic/rubber stock feet to brass cones and place it on a maple board, the thing really starts to sing.

That's why I rated changing out the feet/damping board over the outboard motor supply.  I think it's more beneficial overall to start with...and more cost effective in totality as improvements go.

Rim:
The construction of the plinth on the 12XX series is such that you would be throwing out a major portion of the damping system.  There are wooden (and corian) bases which go around the stock plinth which would dress things up if the stock look is not your cup of tea.  Personally, I don't mind the stock retro look.  I wouldn't throw out the stock base however as it serves a very useful purpose.  I also would not toss out the stock arm as the bearings in the double gimbal are top notch and with the rewire and damping tray it is very high quality.  Plus you have controls that actualy work and are easy to use.

Hey John would you say the brass cones work better than the Isonoe feet sold by kevin?If so where did you purchase your cones from?Just bought a mk5 and I'm about to start modifying it.Regards derockster

Don't noe (ha) about the Isonoes...got my feet at Parts Express.  Quite inexpensive.

  funny John.

the sp10 was designed to be used w/any diy plinth - you could buy it w/o a plinth.  i think that whatever custom plinth you made for a 1200, you would have to keep the original plinth, as has been stated.

re: p/s, i suspect you could wire the 1200's motor direct w/an outboard hewlett packard lab-grade p/s, that could be set at 21v, & this would prowide excellent performance.  this is how i power the origin-live dc motor kit on my oracle.  (except it's not set at 21v.)  these can be found cheap on ebay, often for ~$100, or even less...

  Yes you could certainly use a lab-grade p/s connected to the main 21V rail that goes to the ICs etc that drive the motor. But, with a variable p/s might there not be a danger of it getting inadvertently varied upwards and frying the circuits?

they have meters - you can see the woltage setting...

Yeah, Dave over there (the proprietor of Sound HiFi) is quite an enthusiastic endorser of the Technics SL-1200.

He's got some novel (and reasonably priced) armboards to fit Rega, Linn/Jelco and SME's to the venerable deck, too.
