This morning's #electronics #repair and refurbish: phono preamplifier out of an Onkyo A-8470 (1988). I don't think the brown goo is the usual corrosive/conductive glue. Still, I removed most of it, if only to get better soldering access.
I replaced all of the elec and styroflex caps. The former all had high ESR and the latter were all over the place in capacity, indicating overheating. The cercaps also mount much more nicely and without sleeves. The wiring I left glued.
