We had Richard Burns install it when he was looking over the unit. He installed a toggle switch on the rear but I don't know what he did internally.

Can you please explain the way you connected the Packburn a bit more in detail. You mentioned a "bypass RIIA", what's that??? Is that something I can buy or use?? Hope to hear from you once again!

But I remember being impressed with the unit once we had the 'bypass RIAA' switch installed. The click removal was quite impressive and the NR, just like software NR, was best used sparingly & in small doses. If you need a quick, cleaner-but-not-perfect pass of a disc, I think the Packburn can still serve in this capacity.
