It's worked flawlessly since I finished the restoration, but suddenly...... This morning, when pressing ON, immediately the solenoid activates and lowers the arm. ie, it doesn't wait until it reaches the beginning of the LP to lower the arm.

Ok, she's done! Absolutely flawless. This has better sound than all the BG4002's and BG6000's I've done. I am astounded. And the cartridge is nothing special - an original B&O MMC20E. I was thinking of putting in Cardas cables, but to be honest, I can't imagine what an improvement over this would sound like. For me, this is my

No, you must NOT press down the vertical catch ("C" in Section 3 of the BeoGram 4002 Guide), not at all. You must push it UP, and hold it UP all the time while you are balancing it.
