The Achilles heel of that biasing technique is that the emitter currents of the pair of pnp's is affected by the noise on the 20V supply. The 20V supply noise is only attenuated by a factor of 5 or so when both transistors have equal collector currents. I have both an LTC evaluation board for the

Are you sure? According to my 1982-1986 catalogs, the combination of a HP3586A/B, HP85 and an optional HP3336A/B is called a HP3046A/B. In 1980 there was a HP3040A which was a network analyzer that used the HP3330A/B synthesizer and the HP3570A/B selective level meter... with no computer.

Paul, Your expectation works for text attachments. But binary attachments (e.g., jpg) expand about 33%. That's 8/6, or log2(256)/log2(64), due to base64 encoding of 8-bit bytes. In general, large attachments on this list are ok. It's just that when they are above 128k they are temporarily
