-MKS 4000 electronics upgrade kit (have not purchased yet).
I'm planning a trip to repair an ailing Paramount ME. The existing electronics are probably fine (suspected cause is cabling, diagnosed elsewhere on this forum). In the event that cabling is not the problem, and an electronics upgrade could fix the issue, a "just-in-case" purchase might save me a trip.
In the event that cable adjustments solve our problems, I'd like to know whether I could return an unopened / unused MKS 4000 upgrade kit for refund.
