I'll have to dig it out and post it.

PCB is designed for 1590BB (vertical). For me, there is definitely not enough gain with default schematic values (check frequency response plots to see a difference). So I changed IC1A 8k2 resistor to 15k, IC1B 2k7 to 6k8 and 3n3 to 1n5. This gave me around +10dB (see the graph below). <br />I also find a tone stack adjustment range quite limited, especially for mids, but I left it as is.

The image of the transistor for the bc547 isn't the right way round for the bc547bs i have. It shows the emitter and bass legs are on the opposite side. Not that it should matter if you are checking your pinouts! Its the correct way round for rhe 2n5088/89s and bc550s i have if you are subbing the 547.
