Those amps (I think they're called the SA-360?) are quite rare. It seems they were only sold during the changeover from mono to stereo. Sherwood sold a model (S-4400, I believe. I've got one somewhere.) which had a mono amp section with a stereo preamp. This allowed the buyer - who, perhaps, couldn't afford stereo or was unsure if it would take hold in the marketplace, to upgrade to stereo later by purchasing the S-360 power amp. I don't think Sherwood ever intended for the S-360 to be sold in pairs since, to the best of my knowledge, they never made a stand-alone stereo tube preamp. After stereo was better established, they only offered stereo integrateds and receivers.

Yes, this is correct. The S-4400 was basically an S-5000 with only one output transformer, which was beefier, and wired for PPP operation. The preamp was the same. The S-360 was the upgrade to complete the rig and make it stereo. IIRC, the S-5000 was $189 without case, and the S-4400 was $159. The S-360 was $59 I think.... So, you can see their strategy. And yes, the S-360 is as rare as rocking horse shit, but not as rare as the S-1060, which I've never seen. I just managed to finally get my hands on an S-360 after years of looking for one in good shape and with the original cover. I paid more for it than I've ever paid for any Sherwood amp.
I would LOVE to see an S-1060, 6x7189 output in PPP operation for 60 watts. Must be friggin' awseome.
You got me curious so I pulled a couple of pics off the web.
The S-1060 looks as if there are only two tubes in the preamp section, two drivers/phase inverters, and six 7189 output tubes for a total of 10 (no tube rectifier? ). The S-5000 with big iron and 7189 outputs has five preamp tubes, two drivers/phase inverters, four 7189 outputs, and a GZ34 rectifier for a total of 12 tubes.
Judging purely from a parts selection perspective (having never heard a S-1060) I would bet the S-5000 betters it sonically within its power rating.
Doesn't matter, I'm keeping my Samra'd S-5000 F-O-R-E-V-E-R............
Or at least until I'm deaf or horizontal.

Sounds like they started with a mono version of the S5500 preamp.

He offered it to me for, I think $300, but that was back in the mid 90's and I thought that was way too much. Of course it's been a while so I guess it's possible that it was a preamp with a mono amp on the same chassis. Anyway, since I didn't get the amps until a few years later there was no pressing need for the preamp, although it looked pretty cool with the faux leather faceplate.And yes S-360 is correct because it's on the Radiomuseum website. I couldn't recall the exact model number. There are also a few threads about the amp here if you search this forum.

With that faceplate it would likely be from their earliest days and mono.
