P/N 30-4178 is also used in American models 29 and 45.
The Model 45 schematic does not give the values of the condensers, but the 29 schematic does.
The first cap is .01 uF or 10 nF.
The third cap is 3000 pF or 3 nF.
The second is nearly impossible to make out. It is either .02 uF, .03 uF, or .05 uF. (20, 30, or 50 nF, respectively).
I believe I would split the difference and use .03 uF for the second one. It isn't going to make that much of a difference in tone quality, especially since these are not high fidelity units anyway.
