[ARC5] transistors

[Kenneth G. Gordon]

I still have some OPAMPS here which are exactly the same form 
factor as a domino but are 3 times as thick. They have gold plated 
pins, but only about 7 of them, and are "potted" in some form of 
black epoxy.

These were used in a USGS seismic amplifier. Can't remember 
who made them, but it may have been Burr-Brown...

They work quite well, although their bandwidth is somewhat 
limited.
