Off The Record
Bought this TT from Germany off the ebay a month ago, and from the day one had issues. First, it did burn out its original PSU of 16V - 160mA, just after five minutes of working!!
Then I tried another PSU I had at hand, AC/AC but with 18V - 200mA - Thorens did kill this one too!?!
Power at home (new building, new wires) is always stable 230V, and I have all my devices attached into the power conditioner. Never a single issue with any of those; amps., preamps., players, other turntables!
After reading about similar issues with this model on other forums, I've decided to replace crucial OP AMP - LM324 op-amp IC, but two others on the board as well; TL084, and TL071.
In the meantime also bought the ultimate PSU by Thorens TPN 2000, and... with it TT works but slow on both speeds!?! Also TPN PSU is getting warm too soon.
Found another AC/AC transformer, of 16V 600mA, switched in, turned on, and it was playing great, stable speed for about five minutes... and PSU DIED! Again!?
While working on the PCB board I found nothing suspicious, all caps, and resistors seems fine, nothing burned. Why is this happening is beyond my understanding. I tried to find solution with the guy who sold me this crap (although turntable looks great, neat and well preserved), and he proposed to send it back to him. However, I would like to find a solution, and make it work if possible.
Anyone knows or have an idea what the hell is going on here!? Thanks!
