How Hot is Too Hot - Diablo 300 - Hell Hath Some Fury…!

So I’m following the advice of most of you guys here…and the advice from Gryphon and leaving this thing on or in standby mode only unplugging it when I go out of town.

During normal listening, it gets real hot. Too hot to keep your hands on the heat syncs for more than a five count.
One devil to another… Is that ok…?

Granted, we are in Miami and normal room temp is in the upper 70’s most of the time.

How hot does your Gryphon get…?

Nelson Pass says 5-6 sec for the palms on the heatsinks is perfect amount of Class-A bias, for the size of the heatsinks, means the heatsink are around 55c after 1hr at normal room temp.
That was his response to me with an email when I was biasing from memory a Threshold Statis 500 or something he designed as the emitter resistors at the bottom were impossible to measure safely so I could only go with heatsink temp.
