Paul Garafola Posted January 14 Report Share Posted January 14 My 4018 cap screws on easily & perfectly to my MMP-B and MMP-C pre-amps - and here's where it's giving me resistance on the MMP-A. (see photos) In this moment, I do not want to take the chance on giving it more force, in order for it to seat as it should. I don't want to make the problem worse. If you've had this occur, is it an actual problem - or will it seat perfectly if I continue turning it past the resistance? Did yours? If you'd had this exact situation occur, what was the solution? Thanks for your help. - Paul Quote Link to comment Share on other sites More sharing options...
Roderick Matte Posted January 14 Report Share Posted January 14 The MMP-A threads would perhaps need a subtle brushing to clear any possible debris. I'd use a slight dab of ceramic thread/bike chain lubricant. Difficult to gauge when torque is critical- .2 Nm would be a good start. Otherwise, DPA are usually quite precise in threading. I'd contact DPA if nothing else. Quote Link to comment Share on other sites More sharing options...
Paul Garafola Posted January 14 Author Report Share Posted January 14 Hi Roderick, Yeah, I cleared and cleaned the threads on the MMP-A and still no progress. I would try the lubricant, but I really think the primary and only issue is a faulty thread. So you've had this exact issue and the lubricant actually worked - and the capsule then attached easily?? (Yeah, if there's not a solid solution that people have succeeded with, then I'll just send it back for a warranty replacement. But obviously, I'd like to not have to do that.) Thanks for your reply. - Paul - Quote Link to comment Share on other sites More sharing options...
