No, no. I'm no engineer, nor do I play one on TV. And I'm afraid I don't have time right now for a detailed answer, but -
Yes there is a limit on how high you go in uF. 22 uF for 20 is perfectly fine. 200 uF for 20 is too much. In tube rectifier power supplies, you risk causing problems when you go too high in uF so try to keep it as close to original as possible. 450V is OK to replace 350V, but in the case of electrolytics, there really is no need.
Most (if not all) capacitors have a working voltage rated in DC. Some are rated for AC applications (motor start, motor run, "safety" capacitors) and will have an AC rating as well. Just because a capacitor is rated in VDC does not make it an electrolytic.
Mike, Terry...help me out here...
