Hi, If you do (or did) manage to get a schematic, please share!

Meanwhile, if it helps, yes it does indeed have 4 JAN 6922's inside, also printed neatly on the board is 'class A balanced linear cascode F22 preamplifier'

When I re-capped mine I took (before) pictures, but only of the top of the board (No I dont know why either.) if those are useful?

Cheers

Andy
