The 120uF caps are not completely in parallel though, R17 sits between the positive legs (either a pair of resistors or a choke), so I don't know if you could have different values on each side. I'll have to leave that question to the experts

In Tubelab SSE, the PS has similar thing going on; the choke is it between 2 major power caps. C1 is 47uf and C2 is 120uf. And the motor run is in parallel with 120uf cap.
GSG:
C10 is the 22uf cap. C8 and C9 are 120uf caps and R17 sits between them. I was wondering about putting a 80uf(or may be smaller value) motor run cap in parallel with C9 and entirely replacing C10 with a 20-30uf motor run. I wonder what the experts think aswell.
