PDF seems all there, bit annoying that not all the sheets are the same orientation but meh...

Now I've skimmed the manual, I know one thing for sure; I never EVER want to have to open this thing up!

Oh, it's not that bad inside. I've only wrecked one through careless application of a probe.

My toolchain couldn't cope with landscape image inside portrait paper, and I couldn't be bothered to find out why. OTOH I did bother to ensure the rotated pages all have the same orientation, unlike the paper manual.

EDIT: the schematics are A3 resolution(12k*8k, <250kB), and can be turned through a right angle after printing.

I don't want to have to deal with all those unobtainium transistor pairs. Or the discrete analogue PLL. Or the discrete uP. Or the chopper. Or the black magic reference circuit.

Does anybody? But sometimes "needs must".

Is the reference circuit really black magic? ISTR it is pretty standard for that time.

For me, the black magic is in getting the performance they did from the components they used

Agreed, but standard black magic.
