Temp Variations CH to CH

[Zero Cool]

What would be a normal channel to channel temprature variation range?

I just finished my amp and one channel (the stock factory ch.) is running about 101-102 deg F, the repaired channel is running 104-105 Deg F so we are not talking about much 3-4 degree's max.

At what point do you say, ok im cracking the cover open again and checking or resetting BIAS?
