levinson 32 heat

hi there,
i'm trying out a levinson 32 pre and am finding runs incredibly hot. I've been keeping it in standby mode when not listening, as indicated, and it's really hot. Anyone comment on this? is this a normal occurance? Does it need AC or a fan? Also, I have it plugged into a dedicated 20amp line.
Please let me know your experiences with heat and the 32.
Thanks
Chris

I don't know about incredibly hot, but mine does run surprisingly warm for a solid state device. I keep the power supply/control box and the actual preamp box on separate, open shelves, so I don't worry about ventilation. I leave mine active all the time.

Wadia,

Most linestage/preamps are Class A biased. Given the low output of linestages, excessive heat is normally not an issue with solid state linestages. Besides, with the Ref. No. 32, the amplification stage, input switching and volume resistor ladder is in the box that Fmj said is not hot. The box that is hot is the power supply/logic control circuitry box.

The power supply box does get somewhat hot, but the kind of heat Fmj is reporting (even the knobs are warm to the touch) is not typical of normal running condition.
