That, I think, is the earlier version. I've never tried to dig out the
sealant to repair one.

Which, IIRC, is connected to the other end of the winding that the red wire
connects to.

If you need any information (pinouts, testpoints, etc), feel free to ask.


Thanks, but it's fixed and working, and I bought 'your' CD a while ago due
time that was very helpfull. 
Had to wire all the conductor paths on the cardreader pcb.
But I made notes about the head connections for who wants to dig.
Serial is 1509S07*** but I have another one with the serial 1506S05*** witch
has the head filled with epoxy.
