Hi
I built this around a week ago & found I was turning the Filter knob fully CCW where the most Bass Is.
It was just very Thin & Trebly.
I have studied half a dozen different vero's of the original online & he definitely uses a 4u7 Electro from 2N5457 Source to Ground instead of 2u2. It also appears that he might use an 4u7 Electro instead of 2u2 from BC108B Emitter to Ground.

2N5457 bias to 4.84v
BC108B bias to 4.54v
My 2 Cents!
