Hey this could be a positive, after you have cleaned up the mess of course, these amps really respond very well to a set of Black Diamond Racing Cones #4s, I am running a set under my daughters 302 and a friends amp just like yours if these do not fit the bill try a set of Herbies Tenderfeet.
I'm melting!!
Just reached for the controls of my Jolida102 and came away with oozing black slime. The rubber vibration dampening feet seem all to have melted. Scraped them off. Replaced with baby-food container caps. I assume this will work? Shouldn't rubber designed for hot amps be able to resist heat? (or is this just what happens as they age ...)
