there is a resistor that causes a similar problem at r216 which is 0.33ohm,worth a check with a meter

just fixed it   ... the last cap job that was done on it must have been rushed... When the cap on the neck pcb was installed they did not mount it flush and the result was it being pushed in and tearing the pad.


thanks for all the help grantspain......
