SWR Basic Black schematics need!

[Ramses3]

Hi everyone! I'm looking for the schematic of an SWR Basic Black amplifier.
I got one in pretty bad condition and it's missing some components.
The files I found online are incomplete and don't include the effects loop or the power supply section.
Does anyone happen to have a full copy they could share? Thanks!!

Does anyone happen to have a full copy they could share?

There's 2 pdf's with schematics, items 4 and 5, on this tube amp site. 4 is the power amp section, 5 is the preamp section which has the Send and Receive connections for effects. Hope this helps.:

For folk passing thru, here's the main schematic index for over 100 brands of tube amps. Also has schematics for effects and solid state amps.

Note that it looks to me like there may be some parts missing from that schematic, specifically the effects send portion.

There may also be a version with a series effects loop, though I don’t know how many (if any significant numbers) were built.
