There's no way to insert a probe, but based on the temperature of the metal enclosure itself, I would guess that it gets to ~60-70 degrees C while running. The unit is *very* heavy and has a big audio transformer inside as well. I haven't taken it apart yet, but the amplification path is purely analog and likely not very difficult to fix; it's the DAC/digital side I'm worried about. --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
