Gone Fishing
So after 40 years of almost daily use my turntable has finally died. All I've had to do is replace the belt and oil periodically. Guess I've been lucky knowing the problems that people have had over the years with the speed controller failing.
I turned the deck on yesterday to find both the 33 and 45 rpm leds light up simultaneously, then fade and go out. I don't like to move the deck due to the sprung sub chassis being so flimsy and the springs are now unobtainable, but I decided to have a bash at repairing the controller.
So last night I removed the outer and inner platter and inserted the original spindle hole plug to stop oil spillage. Then I locked the sub chassis down with the original transit bolts.
I then stood the deck on its side to reveal the controller cover. Removed this, then the 3 screws holding the pcb to the underside of the plinth.
Dropped the pcb down and disconnected the wires to the mains and pulley. I now have the controller pcb on the bench. Looks like the 15k resistors, 22uf axial caps and a few more resistors need replacing. One TIP49 looks like it's been cooked too. I've ordered parts this morning from cricklewood with the exception of the TIP49 ( obsolete) and got a substitute.
I will post up some photos later.
