Well, I've been playing with GE MVP's, Exec II's and Mastr II's for years and never had a casting develop whiskers... until now. This was a VHF high band MVP and when I took it apart, there was one whisker that had to go an inch long. That particular helical section was completely "dead" to tuning. Many more smaller ones in there as well.
I'm not sure if there's a good solution short of another casting, but I cleaned them out with a brush and am now running the casting and covers through the dishwasher (before my wife gets home!). Hopefully this will keep things at bay for several years. Chuck WB2EDV
