I put together a power amplifier with FET output boards that has a couple of the transistors on one of the channel boards running hotter then any of the others on the same channel as well as the other channel. The variance is about 10-15 degrees on my laser and does fluctuate over time rising and then cooling down. I built a few amps with the same board and never had this issue. The sound does not change in any way that I can hear. Just wondering if this is normal as these are Chinese boards. I do not have a schematic but have indicated the link to the boards purchased. Anyone have thoughts on this issue Thanks Wayne
