Summer is near, says my #synthesizer.

The overheating problem of my #Roland #JDXA is back. I put in a miniature amateur heat sink and later even a fan. Doesn't help 100%. When it overheats, da AD section between the analog synth parts and the FX go crazy, producing 0dBFS noise.

I really don't know what to do now, except for replacing the digital board… which might be an expensive thing to do. And even worse, it won't be a sustainable fix, because the new board will be broken by design the very same way. Unfortunately, the JD-XA has become my work horse for a specific music project I play in – live.

Photo shows a “heat sink” to some kind of power supply / voltage regulator chip that does weird stuff when too hot and then the 4ch AD chip goes mad.

Would do #fedihelp #electronics #nerds think? Is there a non-SMD-replacement to that regulator that I could fit in and mount it somewhere else, perhaps on piece of metal?
