Assembled all of it & somehow managed to misplace the rotary control board.
They've made a few near-substitutions in the parts list, notably the XYZ board part #46 - 1 piece 510K is now a 1M resistor, this was the last one I soldered, presuming uprated intentionally. There's a few more with non-standard banding, but multimeter confirmed values. Also the Control board has downrated the capacitance of #6 from 330pF to 300pF and of parts #9 - now 10V instead of 16V rating, presumably availability. The fuses are 1A and 2A fast-acting fuses, annoyingly must be desoldered after they've blown, unsure of the voltage tolerance. Hoping the control board turns up, otherwise I have a paperweight I can't tune.
