Default Re: RSC Guitar Amplifier.

I have an idea that the company, which traded under the name RSC, changed what they claimed the letters stood for from Radio Supply Co to Realistic Sound Centres, at some point in the 1970's.

I have a few transformers which I bought from them - I'm sure they had their own winding shop.

As noted above, Radio Component Specialists is another outfit.

As to the valve line-up, the valveholders with pins 4 & 5 linked must be ECC83's (the heater power supplied betwen pin 9 and pins 4 & 5. The valveholder with several (4?) connections to the mains transformer - possibly with low-value resistors in series with a couple of wires - must be the EZ81. The remaining two valveholders, by elimination, must be the EL84's.
