I'm thinking in your case, is that engaged correctly on the b sides, because if it isn't, the gripper will likely wobble and probably shove the record back in the wrong slot.

The E is more like the 78 mechanism, in that the gripper "switches sides" purelymechanically at the carriage transitions from moving one direction to moving theother. So it goes down the rack one way, picking up the A sides, then at the endof travel the lug assembly is pushed to the opposite side and it goes back in theother direction picking up the B sides. The way I can imagine that the carriagecould be properly centered on the rack, pick the A sides correctly, but be misaligned for the B sides (or vice versa in this case) would be if the trip leverand selection levers for that side are out of alignment in relation to the alignmentof the "good" side.
Hi Dave...Are you referring to the levers on the mechanism itself that are out of alignment? If so how do you correct this? Would those levers have anything to do with the gripper position when it returns a record? This is driving me crazy trying to figure out. Thanks for your reply

I've looked all over for a manual for this type mechanism and I can't find it,so forgive the colloquial description. I'm talking about the levers that hangunder the carriage, which strike the selection levers on the base. One forthe even levers, one for the odd ones. If the mechanism is in perfect alignment, such that the gripper is centered over the record in the rack whenplaying the even numbers, you need to check if it is also centered whenplaying the odd numbers. My bet is that it is not stopping in the centeredposition when playing odd numbers. The gripper can still pick up therecord, but the record will catch the rack divider on the way back into therack and will therefore peel off into the wrong slot. This would indicate that the hanging lever for the odd selections is out of adjustment left-to-right,and is causing the carriage to stop in a non-centered position. You might haveto remove the gripper motor and move the gripper manually (slowly) toget a clear picture of whether it's centered or not. If the hanging trip lever is out of adjustment, I believe there is a adjustmentscrew you can turn with an Allen wrench to adjust its trip point in and out.Hope this is more helpful than confusing. Can't find the damn manual. :-)
Hi Nigel, are you suggesting something is loose at the base of the gripper arm? The E is the same as the G model on the gripper. Im not sure about the continental. Thank you - Jamie

Hi Jamie,
When a record is returned to the rack, the casting at the back of the gripper arm has 2 cut outs and depending on a or b side, a bar will sit in one of the castings which duly guides the correct side of the record to the turntable. On reverse, it does the same. What I'm thinking is maybe the bar that sits in the cut out on the casting is either bent, stiff, or it's linkage not engaging, forcing the gripper to not centre correctly on its return.
If you play a b side and reject it and just before the record is put into the rack, power off and with your hand manually try to line the gripper up correctly. Don't force anything. If there is any play there where you can waggle the gripper arm between the correct and the wrong slot, then that's likely to be your problem.
Nigel
