Too much bass

Hey friends
I repaired Nsm- 120 prestige, and now have questions, Amp 70s bb. I managed to get a sound for it but there is too much bass in the sound and also too much "sound from the disc" if anyone could say which component should be researched / replaced. I have already changed a few of the capacitor. thank you in advance

Greeting!
Old problems have been solved, but there are new ones. I choose the number 6 and the b-side, the tray can not find all .All other numbers is working (a / b.)
I thought the audited wires and switches, I can not find reason .Do someone had the same fault.

I got the same problem as you vellu! If I will find the solution (searching for it) I will write here.
