4002 Tracking issue ?

14 replies

Martin, Thanks for your patience, I am new to Electronics repair. With the belt off and the stylus on a record, checked the voltage across the terminals it was showing 22.7v , so back to one of my earlier questions. Where do I source this bulb?  Did it look soldered or socketed I have not seen both so I am unable to tell?

Confirmed then.
And it looks soldered.

I don't have that lamp in the drawer but I would try something like this, in the 24V 40mA type:

Martin, got the bulb from the UK (thank for the tip) installing it was really something. The bulb is made into the black plastic lid of the housing, it

was epoxied in with the two wires coming out the back. I was able to chisel the old bulb out clean out the hole with a Dremel tool. After inserting

the leads of the new bulb through I used  clear silicon RTV to secure the new bulb in the hole where the factory orig. was. Of course the leads had to

be soldered to the circuit board as well. Now it cues up and tracks just fine. Since I have never had it play all the way across a record I never came

across another problem. Once the arm tracks all the way across the record it does not want to lift. Now you can gently touch the shutter mechanism

under the arm and it will lift and return and shut down. Does the new lamp need to be aimed  or what any ideas? Seems to be mechanical adjustment.

There is an adjustment for the interrupter.
See the service manual (which I don't have at hand right now).
