Mike, those are the primary candidates for that glue I'm talking about. That stuff is just evil. I'm telling ya, if you care much about those units, you'll get that crap out of there. It's eating your traces. It's eating any leads it's touching. And it's becoming conductive itself. Vintage audio forums are chocked full of horror stories because of that glue. I stick to the Marantz stuff because they never used it and you don't have to get into chemicals and hours of meticulously removing that stuff. It's real easy to identify. It almost has the consistency of that expending foam insulation. Lots of air bubbles. It's very hard and cracks and crumbles instead of having any pliability.
Magical Marantz 22## receivers
Why is it generally accepted that caps in a vintage speaker crossover should be replaced but some how these mid-fi (at best) 70’s vintage receivers seem to get better (and more expensive) with no maintenance. I would love to see someone bench test one of these beauties with the “tube like” sound.
