Hi Steve,
I unplugged all except pwr. still .7v, I checked this at the circuit 
board plig-in and the same.
Following the circuit back from the board  4 pin jack there are 2 
surface mount components.
The first  closest to the jack end of the circuit measures .70 one one 
side and .73 on the other
pos a chip res. When I check the 2nd chip component I measure the .73 
and 4.6v on the outer side.
This suspect chip has a marking of EO1 or E01 on it, very hard to see. 
Might be a cap. Any idea
what it is and it's value ?
