* 470k logarithmic pots maybe hard to find or expensive. You could just get a A500k and ask your
vendor to get one of around 470k as most pots are rated +/- 10% or more.
Note that the original uses 400V axial electrolytes for C5 and C7 capacitors. They will fit in an upright
position, but I advise you use radial electrolyte capacitors and choose the good ones like Elna, Fine
Gold Panasonics etc. that will fit.
C6 is originally a foil capacitor (eg. Mallory), but a 10n SMF sounds
great.
Also note that the resistors R2 to R6 in the original are carbon film ones (eg. Piher). They will not
directly fit, but you could put them in an upright position and then they will fit.
Lastly, R1 is not in the original. It is a pull down resistor used to prevent the pop when switching the
true bypass switch and can be left out without any problem. Also R7 is added as offset for the sag
(see the chapter “power section”). You should not waste an exp ensive carbon resistor on them!
