Back in Jan I picked up an early model(red letter) 129x and have begun a recap. Someone previously had done a partial job of it. The can electrolytic was 3 sections of 20mf, 2 at 250V and one at 25V, with a separate 8mf/250V cap for one of the 10mf sections. My question is, is having 20mf of filtering ok on this instead of the 10mf? I've heard some things of over filtering and that some issues can arise concerning charge/discharge times and in-rush current at power up. I can get the 10mf caps if I need to, but I'd like to know what problems can come up with 20mf instead.

Thanks,
