Re: Grundig TK27 - Low audio output
My TK 27L volume control works fine, with increasing volume throughout the adjustment range. Compared to similar TK mono recorders (like TK 14, TK 23 etc) it is noticeably louder, at volume setting 2 it is more than loud enough for normal listening.
The volume control pot is driven by the volume control knob via a plastic drive belt/strap, make sure your drive belt is driving the pot correctly.
