The nice thing about the amplifier circuits that Bruce has been modelling lately is the performance they can achieve using ordinary 2N3904/2N2222-class bipolars, with no exotic hardware or twitchy parameter dependencies. There is some work in progress now that will make inexpensive, plug-and-play isolation/distribution amps available to any who are interested, with S12 and additive-PN performance competitive with the best commercial and NIST designs.
