[QUOTE="marantz123, post: 1124083, member: 16849"] Wow..... some history this amp has had ! At a guess, a pot-plant once lived atop this amplifier, probably sat on a little "doiley" which somebodys mother or wife crocheted..imagine how cute that must've looked... especially with a well-watered plant ... The top of the board looks like its had some water damage which possibly dissolved some of the thermal compound (very first pic, look at the heatsink), this solution washed through the hole in the heatsink, and someone used a hairdryer to dry up the amp and in the process forced the spread of the gunk under the board. No need to replace those ceramic disc capacitors, they are likely to be fine. Instructions came with plant...place in warm place, keep well watered. [/QUOTE]
