I have a similar but opposite problem with my M100-A. When the pickupsets down on the B-side, it frequently hops inward a couple grooves. It'sbeen doing this literally for decades and it defies my analysis. I even removedthe little spring that is supposed to nudge the stylus into the groove onolder records without a lead-in groove and that had no effect other than tooccasionally keep the A-side from engaging the groove. So the spring isback. I find that the problem is worse on the first B-side that's played afteran A-side, so sometimes I'll play multiple B-sides at a time. I'm resistingre-setting-up the mechanism, because conventional wisdom is that unlessthe the mechanism has endured some "traumatic" event, you're just as likely to make matters worse than better. As to the pickup grease, I've never seen anything in Seeburg literature thatdiscusses it's purpose, and their documentation is first rate. I had my pickuprebuilt by Wes-Tech years ago (mine was the first one Wes had done, and nowI understand that they no longer do them under the new ownership). Except for the detached armature it sounded pretty much the same as before, sansgrease. There is some blasting on high frequencies on shellac records from thelate 30s and early 40s, but on mid to late 50s, high-fidelity vinyl records the highfrequencies sound fine. So I attribute the distortion to groove wear, and stilldon't know what the grease is really for. BTW, if you want a good demonstrator for how good this machine can sound,look for Al Caiola's "El Cumbanchero" (RCA Victor E2-FB-7229 / 20-5400) whichis fairly common as a vinyl DJ pressing. It sounds fantastic.
