Wow, thats exatcly what mine does too.

I bought some new pairs of phono leads, swapped out the ones from the dockingcage. Still I have the left channel (front) out from time to time.
As you say, the only way to fix it is to pull the empeg out and put it backi in again.

I checked the internal connections in the Empeg too, and also noticed that the small
board under the drives was a bit 'wiggely', pushed it back in place. Can't say it helped much.

I have a liiiitle feeling that it came with 2.0, or it might hust be bad timing because I didn't have it before that. (In time, at least.)

Waiting for new my MKII.
