Default mixing caps?

on my phoenix gold amp i've just changed one bank of caps (originally 2200uf 16v) to 35v caps. i havn't changed the good side but would it hurt the amp having higher voltage caps on opposite sides of circuit board?

also, the 47ohm resisters look a bit burnt but are reading correct on the multimetre, are these ok?

Im sure it wont hurt the amp, but my experience (only one attempt) made the amp oscilliate like crazy when just replacing one bank of caps.

It creates a frequency on its own and usually generates a lot of heat and or noise.
