You can never have enough good quality screwdrivers, to get the ideal fit in any slot - that way you don't damage the screws, or scratch the woodwork when an ill-fitting screwdriver tip slips...I had the same problem when opening my Rochelle. I found the choice of screwdriver was the key. A good quality Philip's head screwdriver with sharply defined edges on the "cross", and a precise fit to the screw did the trick. A sloppy fitting screwdriver just turned without getting traction, and chewed up the screwhead (I had to replace several screws when I reassembled it)
Could anyone advise me on what should my next step be?
I dread to think how many I've got!
