I don't think WIMA MKS come as big as 33uf, 16V (C6 in the 485). You can substitute two polarized electrolytic caps for one non-polar. Wire them in *series* with the '+' terminals tied together and using the two '-' terminals in the circuit. In series the capacitance is halved and the voltage doubled. So, two 68 uf 16V polars in series approximate one 33 uf non-polar 32V. No problem that the voltage is doubled. The main problem with this is just physical space. Be creative.
