in a quick morning scan with no coffee yet, I say go for the option which minimizes possible gain errors.

do it!

JR, this sounds very interesting. Judging by the sound of the Pico, it would seem that the VCA's day has arrived, and I don't doubt it could sound very good. Keep it up.

No problems in the Carolina's; Louisiana is a 12-14 hour drive from here. We got 6-12" of rain last week as Fay blew back through. Looks like the 'H' storm could come in here next week though.

Wow JR, that schematic is very interesting. Any of the D series info is very hard to find, and this is the first technical info I've ever heard of in reference to early steel tape recording. I recall info about the British doing this, but don't think I've heard about it in the US.

Wow, an ERPI man!

Good stuff! I have spent far too much time collecting original amps, documentation, and period trade literature. Seems to be the only way to put the pieces together. At some point I started tracking various manufacturers preamp products, and continue to narrow in on exact production dates and major ...

Nice compilation. Here are some corrections: The WE 8-C is a 1920's amplifier. 'Early RCA 1940's is somewhat incorrect; that's the BA-1A from 1945. There are 4 previous generations of AC powered RCA, and at least 2 DC powered before that so I'd call it mid-period RCA. 'Langevin 1949' should be 1947....

John, this is very intriguing. Please keep it up.
