Repairing a beam-of-light turntable
#3

Well, I took the turn table apart , cleaned and oiled it up. I took the idler wheels off and sanded them down a bit. So now the record changing is functional and quiet. I found two burnt out bulbs the one for turn table speed and the beam-of-light bulb. I had an incorrect bulb to replace the beam-of-light bulb. So I could test the light sensor and it was putting out .042 volts. I tried a playing a 78 and got no sound. I checked the needle/mirror assembly and found rock rubber bushings. Worst I found the needle tang was only loosely attached the to mirror and could be wiggled about 45 degrees. So I rigged up some new bushing and epoxy-ed the needle tang back on to the mirror. So I tried playing a 78 again and I still got no sound from 78 but I did get a loud hum from my work light. I've owned this console for over ten years and I've totally re-capped it. It plays well but I'll have to wait and see if West Tech has replacement bulbs before I can get the phonograph to work.

Just to make sure, you chose either 4 ohm into 5K or into 10K? (blk-org or blk-grn)morzh — 06:23 PM
