Instead of throwing these out, here are a collection of older PMI, TI, and ST audio switching and driver IC's, listed in the hopes someone will or can use them. I have found many obscure components on here that have rescued otherwise dead equipment; I am returning the courtessy of preservation.

These were removed from a 360 Systems ShortCut digital audio editor I sadly scrapped many years ago. It had a digital problem and wouldn't boot, so was parted out for spares of another on-hand. These were all socketed, as they weren't cheap at the time, and hence were easy to remove without damage.

Here are, in one sale/lot/whatever:

2 x PMI SSM2402P 14 pin dual analog switches

2 x PMI SSM2141 balanced-to-unbalanced driver or receiver.. i forgot which

2 x PMI SSM2142 balanced-to-unbalanced driver or receiver.. I forgot which

2 x PMI OP249 GP op-amps

1 x DG211CJ quad analog switch - probably for controlling the above, in the original circuit.

4 x ST TL072CN op amp

2 x TI TL072CP op amp

All devices as seen in the TWO pictures are included in this ONE sale. It is for all as seen.

These are used, stored with care for some years, and found yesterday. I have no reason to suspect any are faulty, but they are used, and priced accordingly. Again, a PAL or EPROM or SCSI chip failed in the host unit, and the PSU was used in another unit without issue; The analogue side was fine - so I suspect these chips will be too. It was in a broadcast environment, usually used in BBC radio broadcast interview cars.

Er, no returns? unless you plug these all in, blow them up and find they're all dead? then i'm screwed either way.

Passing on as a courtessy to those who build, maintain, and keep good old stuff alive! Collection from central Canterbury also welcome.
