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

Sorry to hear that.   I would open it and reseat all ribbon and molex connectors.  Nothing to lose.  Could be something as simple as that.  Can you control the volume in variable mode ?   Weird problem

Call Tap Electronics @ 1 (714) 562-7400 - they are an official Teac service center. I think the guy I spoke to was called Sal and he was very helpful in diagnosing my problem.
