The Fine Things are Always Hand Made
Hi: You raise a good question -- I recently refurbished an AW15 and I debated whether to disconnect the capacitors cased in stainless steel little capsules riveted to the chassis and wire in new capacitors at their locations. I decided to go ahead and do that to be sure the capacitors were new and to provide a baseline, but I wonder if anyone out there has left the originals in the circuit and finds them operating as they should. Considering the quality of the set, I would think the originals would perform just as well as the new ones. Has anyone left originals alone? You run the risk of a breakdown/short in a bypass cap, but maybe that isn't a valid worry given the quality of everything else in the set. The caps in the power supply and the two filters in the main chassis should always be replaced, as a matter of course.
