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.
