Hi!

I'm reasonably happy I can split the gear into recognisable blocks by circuit function or complete PCB assembly, but no matter how much I partition the blocks, as "Radio Wrangler' David said, they still seem to sprawl over twice the "paper acreage" I plan for !

I'm looking at two EMI/SE Labs EM102 Oscilloscope Manuals I received this morning for ideas, as I've an oscilloscope input attenuator split over two wafer switch sections, a third wafer in the positive f/b loop between two differential amplifiers, followed by two pairs of cascode/long–tail–pair stages, a balanced delay line and a final balanced amplifier pair, before we go to the final deflection amplifier on PCB U3!
