Holy cow. I've just discovered a whole batch of these electrolytics in a newer Maggy (solid state) that are ALL bad!. Strangely, the thing still kind of worked. So far I've replaced about 18 of various values. If you ever run across a nice early transistor Maggy that has NO output, the first thing to look for is the output caps. Usually a 200-400 mfd value which are directly in series with the output. They're usually shot and replacing these will at least get an output. The last one I got also had a bad main filter cap which was also kind of strange. It had Common Positive. Guess back in those days for a time the common was actually positive vs. negative.

Maybe I'm so new to this stuff that this is old, stale, news, but once you get these newer old Maggies going they sound pretty good and have super bass with the 15" woofers.
