[sdiy] tube ladder

[Paul Perry]

With the classic Moog ladder, it is important to have at least
the top & bottom pair of transistors matched (I don't know why,
unless it is to null out 'unfiltered' signal).
So that might be a problem, if you have to match some of the 
pentodes as well.... but if you DO have a supply of matched pentodes,
go into the lucrative valve compressor business!

There is a thrift store near me, where the ppl ask my advice on mysterious 
electrical stuff (no, never anything good!). One day they had a bag of 
miscellaneous parts, obviously from some young enthusiast who had left home.
Among the stuff was.... AN ACTUAL WOODEN BREADBOARD!
Of course, I don't suppose Bob Pease would let you use even a new shiny
"slab'o'trouble" ;D
