Thorens TD316 Upgrade (modification) with the CF1 Micro Seiki arm:


TD-3xx series: In my opinion, the TD-3xx series is the best turntable ever built for his money. With his heavy sub-chassis and stable frame, a real masterpiece. The turntable TD-316 I've bought, was a second hand (100€) copy and in terrible state. I've refinished the turntable with white cherry veneer, replaced the dustcover, updated the electronic performance to a TD-318 model, placed WBT RCS sockets and seperate ground connector at the back and placed a Micro Seiki CF-1 tone arm on it. The arm is a collectors item and for almost 20years in my possession. At last I've placed a Ortofon MC-10 Super for the finishing touch. The rest is pure labour and my passion for vinyl recordings.I would like to thank Steve of the analogue department for placing the photo's and url on his site.

The following items are modified on the turntable:

  Electronic upgrade to a TD-318. (Quick start button with Blue ring LED)
  Veneer from black to white Cherry wood, with six layer transparent lacquer, all polished.
  Replaced the TP-21 tone arm with a Micro Seiki CF-1 tone arm.
  CEC made mounting plate for the CF-1 tone arm.
  The hole for the old lift switch used for the LP Gear Zero™ tool.
  Placed two WBT 0244 RCA sockets at the rear panel.
  Heavy metal power supply connector and ground terminal placed at the rear panel.
  Ortofon MC-10 Super cartridge for vinyl groove contact.

Technical drawings TD-3xx:
Regarding some technical information, all what I could found on the internet was some bad copies in jpg format and therefore difficult to read. Well now, I redraw the schematics of the TD-3xx series and convert these in useable pdf format. Also the CF-1 Micro Seiki arm base (self-made) is now available in pdf format.
