SoundPure is selling a few Sound Devices 788T-SSD units that all appear to be from the same consignment sale. I just bought one of them, but it appears there are two more available. They initially all look like the same item, but if you look at the 6th picture of each with the hard case open and L-mount batteries showing, you will see those batteries are all from a different trio of 1-9. Mine has batteries 1-3, and also a "1" stenciled onto the SD-branded soft case.

The velcro pulls off cleanly with a little patience and a pair of pliers to grab it.

The one that got away (but not from me):

You can do a no-risk free trial week before you buy, as I did. I dealt with Jack DeRiso and highly recommend him: [email protected]
