Uneven Temperature of 2-channel Parasound A23 Amp

I have a Parasound A23 amp. I noticed that the right channel of the amp is so much cooler than the left channel.

I first noted this when I left the amp for a few hours yesterday. Nothing was playing - just that the amp was on.

Although a bit warmer, the right channel seems also cooler after an hour of playing music.

Has anyone experienced this phenomenon?

Sounds to me like the bias is out of adjustment on one of the channels.

Morgandogge,
Thanks for the compliments.
It could be adjusted by a casual listener, but you would need to find out from Parasound where the bias adjusters are inside the amp.
The only problem that I could see that this might cause would be a slight imbalance, sonically, between the left and right channels.
I would recommend contacting Parasound customer service and asking them about it.
Hope this helps.
