Default MY TT build

Hi All

Thought i would post some pics of my TT build.
The base is 80mm South Australian slate. The platter is 75mm acrylic i got spun up at a near by engineers shop, $$$$!
The bearing is a teres bearing and tone arm is origin live, fully modded.

Ill post some details on the AC sync motor control later.

Now waiting on another piece of slate to house motor and speed control.

Thanks for the kind words. It is alond way off the final dusting and polish

The acrylic was purchased as a block then custom machined. The engineer shop spent 6 hours machining and polishing. The guy was great to deal with and gave me a good price considering the work envolved.

The slate is from Mintaro slate in South Australia. Nice quality stone with no defects in it. Motor is an AC sync motor from ebay. Ill posy some pics of the speed control when its finally built. It is going to be housed in a seperate stone housing that sits neatly along side the TT. My brother is an elec engineer and has programmed some chip to produce the two offset frequencies. Then i used two LM 3886 boards from chipamp.com to amplify the signal. With rthe push of a button i can adjust frequencuy and voltage. Sorry i dont know the fine details, all this DIy electrical is newto me.

Nice table you built.

I did not know that you could still get the bearing from Teres.

Thanks for the kind words.

The TT is pretty much complete. I just need to finalised the wheel for the motor.
The platter spins beautifully with either a fine thread of cotton or with the rim drive using an O-ring. unfortunately it will be a little while until i can do a comparison. Whensetting it up for the first time I managed to brush my hand against the DL103R and snap the entire stylus off!!

The speed control works beautifully and is housed below the motor on the slate motor/speed control housing. The platter get up to full speed within a few seconds, then reduces its voltage output for a smooth ride.

I need to get a hurry on with the HPS 5.1, then maybe some horn speakers
