Thanks... I will certanly give them a go. I am pretty sure the problem I am having is the tape, I get a low (and varying) amplitude signal at the output of the read amplifier, it varies with different tapes, and it's much the same both on the drive in the 11/730 and a standalone TU58 I have. You do realise that I am across the Pond, I hope :-). I am happy to cover postage and packing expenses, of course. > I'm cleaning out the storage unit right now, in preparation for > moving, so I'll keep an eye out for them. When I moved house 3.5 years ago, it took _5_ large removal lorries to carry everything. Oh well... -tony
