1930? General Electric T-12

Good neat job on that cap block. For the buzz: what mfd. electrolytics did you use to replace the old ones? I notice that C18 was originally 2 mfd. Back then mfd's were expensive. You could try bridging that cap with a 10 or 15 mfd. electrolytic and if that kills the buzz, substitute it. I wouldn't go over 10 mfd. for C17, the other 'lytic, as too large a one here can strain the rectifier.
