Saw your request for a schematic on Radiomuseum.org
If you're looking for the original 6L6 version, I should have the Sams (and the other two Sams folders for that matter... I assume they're the quad 6BQ5 and 7868 versions). Schematic of 6BQ5 version of S1000-II is on my website: http://www.audiophool.com/hifistuff.html

Hi Tom
I actually need the quad EL84 version...Did you know that Sherwood made an EL84 mono integrated amp with six EL84s in it? It was like 60 watts.
Honest amplification is better than excessive 2nd order distortion anytime.
I'll see if Sams covers that one - Sherwood schematic is on my page.
S-4000 is a unique one with 6 x EL84, but S-4400 is the really strange one - stereo preamp and single PPP EL84 power amp. S-360 was the companion PPP EL84 power amp.
Did anyone but Manley ever make a stereo amp with PPP EL84s? H-K and Bogen made PPP mono amps and receivers using 12AB5 car radio output tubes. Stromberg made the AR-431 with 4 x EL84, but by then, stereo amps were the ones really selling.
The S-1060 was the one I was thinking of with SIX EL84s. S-4000 was a single pair in P-P.Looks like the original S-1000 was 1957, at least that's when Sams covered it in 345-1. 12AX7s, 12AU7 driver, 6L6GBs. Output tubes and transformers were on the back of the chassis.
Sams shows a revised version in 390-10 (early 1958) as S-1000-II, still with 6L6s, now slanted, with a 6BA8 triode-pentode driver.
And then there's my OTHER brother Darrell, I mean another S-1000-II, with the quad EL84s. It's in Sams 441-14 (1959), and there's a copy of that at Radiomuseum.org. The one I had used a 6BA8 driver, but they may have used the brand new 7199 as well.
And if that's not confusing enough, there are versions of the S1000-II with a pair of 7591s and another with a pair of 7868s. At least they went in another direction with the S-1000-III, with two front panel mike levels and maybe a line output (there's one more speaker tap than they needed for 4-8-16)
