Overgrown Chimp

I built a Tone Vendor MKI with high quality NOS components and carbon comp resistors, except of the charge pump that has modern capacitors and the max1044 ic. I think there is too much background noise when it's on. It sounds great when I play. All the soldering was done well. Is it because of the voltage inverter? Should I try other transistors? Any help would be most appreciated. The transistors are q1) TF78/60 IV with a Hfe:95, Leak:0.3ma q2) sft323 hfe:165, Leak:0.25ma and q3) ac128k hfe:98, Leak:0.6ma
