Anyone know someone that does troubleshooting and repair of old Whites detectors,( coinmaster 6000 series II ). Tried the Sweethome factory twice, but the detector started acting up afew months later, ( both times repaired ). Tried a fellow in Ill. a few years back and that lasted for a few weeks. I don't think Whites has any old timers left that know how to repair the older machines, or maybe they want me to upgrade to something newer. Actually, I have an MXT, but I want the 6000 back in top notch condition. Probably the best machine they made. Thanks for any help.
