Teac UD-503 Volume problem

Hi everyone. I have a teac ud-503 for years. Recently the volume will starting to drop and back to normal randomly after 15-20 mins use. This dac has a pre amp section and can be set to fix or variable. But no matter what setting it is, same thing happened after 15-20 mins use, no no matter using xlr or rca out put.  Any idea about it?

Thanks for your time

Some of the hardware/ instruments i install have weird logic issues , resetting doesn't always work but sometimes leaving them unplugged for a while exorcises the gremlins.   Unplug overnight if you havent already.  

Good luck.
