RE: Echoplex and The Outdoors



It's probably the same problem. Its the temperature inside that ic that
really matters, the outside temperature may not be enough to cool it down.
Clipping that pin fixes it.

And remember, the ventilation you experience standing next to the rack may
not be the same ventilation experienced inside the devices. A well placed
fan is never a bad idea with music gear in the great outdoors. Sunshine on
black metal can transfer a lot of heat inside those guys. A lot of parts
might not fail immediately, but just die a slow steady death in the heat.
