>I'd settle for a readily available, cheap source of good npn and pnp
matched transistor arrays! Why is it that these always seem to go
obsolete? AD821, uA726, THAT co.... even the LM394 is hard to get
nowadays.<

Even the 3046 would be very useful if someone would make it with better
specs.  Hfe = 40 might have been Ok back in the '70s, but not today.  IC
fabrication has advanced a lot in 30 years, why can't someone put 4 or 5
transistors in a 14 pin dip with Hfe around 400 - 500, low Rbe, etc.  

Maybe we can get together as a group, and have a semiconductor fab house
make some for us, with the specs we need.
