Hi again...was wondering if any of you who have restored an au919 have experimented with replacing any of the mylar caps that affect signal shaping with polystyrene or film/foil caps???? Your thoughts would be appreciated

You should PM PunkerX or I could move this thread to the Tuners forum.
Are you prepared to do an alignment?

Most of the mylar caps are fine...the ones I like to change are C43 and C44 on the amp boards, and C01 and C02 on the protection board. Need a good quality 250V polypropylene cap here.
