I've got a bunch (maybe half a dozen) 600 ohm - to

transformers. Nice units, maybe 5 inches tall by 2.5 inches wide, and
potted. Use 4 8/32 screws for mounting.
Is there any use for this stuff? Does anyone want them?

Speaking of which, a friend has a bunch of Tellabs 4201 2-wire to
4-wire hybrids ("Terminating Sets") that he'd like to sell. Maybe
useful to hams? They are switchable for 600 or 900 ohms on the 2-wire
side, and fixed at 600 ohms on the 4-wire side. each module has two
potted transformers, four test jacks, and an edge connector to plug
into a backplane.
