Scopex 4D10 versions.
I have been corresponding with Chris55000 about Scopex 4D10 oscilloscopes.
There were quite a lot of variants of this, an early single board servicing grade scope. Badge engineered and sold by Avo, RS and others.
I had posted a manual in the past apparently with the wrong version circuit diagrams.
The tube fitted seems to have varied with the supply and price situation- Brimar D10-230, Philips D10-363, TFK D10-260, Mullard D10-160.
So I attach the circuit and PCB layouts for the 4D10 and 4D10A versions to clear up any confusion. Chris has the 4D10B, and so I hope he will post that as well.
