Well I went and did it.
I bypassed the large 4700uf power supply caps with .47 HiQ Black Gates and replaced the two 22uf polar caps with two 47uf HiQ and two .47 HiQ nonpolar Black Gates. The sound? Well they need some time but there is a bit of refinement. I am still running the stock opamps.
According to the pic above, I see the 2 4700uf caps and another 2 small,standing caps (still dunno what are they?). But if I not mistaken, I see you replace six (sorry for my noob) caps? So, please help me clarify this and I would appreciate for some real pic
