try the regulator right side torward the back,i believe it says d1135 and also change the diode d-60 to a 18.2v diode andput the old ones across leg 1 and 2 od the regulator.common problem with early model 142 gtl. |

ok now i got some where,unsolder the black ground wire from the power supply,put it through a hole in the chassis,and solder it to the negitive leg of c-304. that will stop that completely. both of these messages are fixes from factory mess ups in the earlyer 142 gtl's |
