After having read nearly all posts  on the subject and having done all mechanical works the TT runs (was dead when I became it), b - u -t  very very slow. Pressing the idler wheel a litle bit to the pulley does not help.  So I suggest there is an electronic problem. There is not really much in that thing , but as I am not an electrician I don't know where I should have a closer look. And where to measure.

Any helpfull hint is much appreciated.
