[sdiy] That Corp transistor arrays

[patchell]

    Oh yes, very useful ;^)

    I am using the THAT 140 (obsolete, replaced by the THAT 240) which has
2 NPN and 2 PNP transistors.  Great for things like simple OTA's (as in
SSM2040 type filters), and other uses.  Although, they are premium priced,
so you need to use them in premimum places.  I have also used the THAT 120
(obsolte, replaced by the THAT 220) for doing PNP expo converters.
Although, for what I used them for, I think hand matched 2n2906's are just
fine.  I have also used the THAT 120 to make preamps.
