Guys, we've been through this before:
1. At our operational temperatures, the shortest lifespan components (besides tubes, the electrolytic capacitors) are expected to last 60,000 hours. Look into temperature derating of capacitors (the "3000 hours" rating is at maximum operational temperature, which we are nowhere near.)
2. The use of the chassis as a heatsink leads to overall lower operational temperatures for the output devices than a typical device using PC-mounted heatsinks inside a chassis. Grab on to some of those, and you'll lose skin, because 60-80 degrees C is not unusual.
3. If 35-40 degrees C is too much for your fingers (the typical temperature of a Lyr 2 knob in a typical room), then I think you need to think twice about having a significant other, since they're gonna run right in the middle of that temperature range. If your room is 85 degrees F, then yes, the temperature will be higher, but it's still nothing to worry about, per point 1 and 2 above.
Bottom line, if we didn't think it would last for twice the warranty period, the warranty would be shorter to reflect that. With well over 100,000 products in the field, our repair tech still only works about 16 hours a week, on all repairs, including internal stuff that failed on the burn-in rack.
