I had ordered this Rega 330B tonearm 3 months ago and after a long wait received this 2 weeks ago. Later this week also received the arm board for mounting the Rega arm on the Thorens table.
Unfortunately the original Thorens arm (TP16) have a somewhat different " Effective Length" compared to the Regas and hence there could be a difference as high as 6mm. The Thorens has a pivot to spindle distance of 216mm and a overhang of 14.5mm. The Regas have 222mm and 15mm. Effectively the original Thorens armboard cannot be used for the Regas and they will not track accurately if used.
When i tried mounting the new armboard little did I realise that there was more trouble on the way. The sub-chassis was blocking the arm below and proper installation was not possible. I had to cut the sub-chassis and bend it by 5mm for the arm to be installed. After this was done was able to level the arm board and suspension. The springs on which the sub-chassis is mounted has become a bit weak over the years and might need replacement too in future.
This Rega arm tracks well and is not flimsy like the TP16 which requires a super high compliance cartridge which are difficult to source. I levelled the platter, suspension and table using a mobile bassed Accelerometer application. Now the x &y are at 0 m/s.
Thanks for looking.
