Eml synthesizers

Sorry guys, I lied. The 3026 is actually a DIP package with 6 NPN
transistors inside. Two of the transistors are precisely matched. EML used
it in their systems for the modulator/ amplitude shaper circuit on the 101
They use the matched pair for the differential input circuit and string the
other 4 into a constant current source to specifically heat the chip in
order for it to work in a constant-temperature environment for stability
purposes.
