Dual 1229 upgrades???

Wow. I have completely rebuilt my Dual, much to must to list and discuss here. Rebuilding the motor, relubing and changing the platter bearing are among a few musts. Also, I use a Grace 747 tone arm on mine. The results were so good, that I sold my Linn LP 12 which had every upgrade known to man. The Dual is last table I will own. I use it every day... amazingly reliable, dead silent in operation, and flawess, stunning, big open sound stage. Don't waste your money on another table. The idler driven Duals, Thorens, and Garrards, were just the best. Email with any questions.

Questions by the truck load including......
Never heard of Grace but I'm showing my neophyte status, so, who has this wonderful arm and most importantly does the auto function still, er, function?
I would be in no position to rebuild the motor or bearing so would need a suitable mechanic. Who do you recommend?
Also, what phono cartridge and phono pre-amp are you using to get those big open soundstages?
I'm interested!

Buy a hardwood base from Bill at fixmydualdotcom ($95), and try swapping out the springs for Edmund Scientific 3/4 inch "unhappy balls" ($19.80 for set of 4), which perfectly fit the wells for the springs in both the tt plinth and the hardwood base. Bill's hardwood base has four small legs that should rest on some type of isolation "feet". Edmund Scientific sells Sorbothane sheets and a single sheet ($19.95) can be cut into many small (even stackable) squares that work fine as feet. Just use a cardboard beer glass coaster under Sorbothane, as it sort of "bleeds/stains" a wee bit. The nice thing about the Sorbothane sheet "feet" is that you can vary the # of squares under each base leg to achieve a level platter surface. I've done this with my Dual 721 with good result.

Thanks for the isolation info Jb0194. I bought (2) Dual's from Bill and he is a quality guy.

I'm not sure Bill agrees with the Norbornene balls in place of the stock springs, but I find greater immunity to footfalls and other extrinsic vibrations.
The direct drives with the EDS1000 motor don't seem stressed by a 3+ pound TTWeights center weight, which really helps tighten the bass. Don't know about the idlers, but a much lighter true clamp may work.
