New Raven AC Owner


Hi,

I am new to Audiogon and I thought I would join to connect to other TW Acustics turntable owners.

I bought a 2007 Raven AC with a Graham Phantom B44 and have put a Clearaudio Accurate cartridge on it. This TT is the biggest upgrade I’ve ever had by some margin. What a fantastic player it is. I’ve had many many turntables over the last 20 years (several LP12’s, Pink Triangle Anniversary, SP10, various Thorens, Rega’s, Gyrodecks and too many others to mention) but non-have given this amount of musicality and sheer detail (except maybe the PT Anni). I compared it to my original “Obsidian” SP10.2 fitted with a 12” Jelco and SPU Royal GM and the comparison took all of 5 minutes! I haven’t compared it the Anni yet though. Too busy enjoying it. I am desperate to get the Jelco SA-750L 12” arm with SPU onto the deck in the rear position though (I have placed a wanted ad for an appropriate armboard for this ;-) )

I have a question for you guys though regarding setup, Should the motor be positioned so that it stretches the belt slightly? Or is there a fixed distance I should put the motor? I understand there are several different lengths of belt and I’m not sure what I have. I have the motor positioned to the left side of the plinth.

I’m sure I’ll have many more questions as I settle into using this player.

Thanks all.

Depending on which belt you have there are different distances. For the short belt I have the motor case 5mm away from the plinth on the left side. For the long belt the manual states 340-350mm from center of platter to center of motor pulley. Check speed and adjust if necessary after.
My manual says the motor pulley to spindle distance should be 340-350 mm. I think I have the long belt.
