I recently shipped my XPA-2 for service after it developed some problem and it was refusing to switch on. Since the item is shipping from Doha and back the cost shipping costs alone are more than the price of a new XPA-2 Gen 3. Based on advice from Emotiva before shipping this unit, I was able to ascertain that some areas and components of the small board housed at the bottom of the amp are burnt out. I have begged Emotiva to replace this little board even if it means charging me for it and my requests have been refused. When the unit was first examined, I was informed that there was absolutely nothing wrong with the unit. I reminded Emotiva that the unit is being used on 230V and wondered whether thats the reason a Emotiva has found no problem with the unit. Later I was told "Our service technician found the following issue:
Replaced bias potentiometers in both channels
Readjusted bias to factory specifications"
I am not an electrical engineer/technician, but I suspect that the little board was neither repaired nor replaced. Having offered to pay for the a new board and having informed Emotiva that the unit has come a long way, I am naturally unhappy with the way things have been handled. Surely looking at that board, this unit will not last long before the same fault or other faults appear?

It sounds like you have been in contact with Emotiva. Have you asked to speak directly with Dan or the technician? I think you would get a better response or at least the ability to discuss the issue over phone which should be easier than trying to handle it through the forum. Dan is pretty good a chiming in when necessary, but not sure your issue will make it back to him right away like a phone call would.

Gentlemen, No one has spoke to me directly about this issue until is was brought to my attention a minute ago... OK, this amplifier was inspected, tested, burned in by two different technicians in order to try to find a problem. None was found. The unit was tested and burned in on both 230 volts and 120 volts for several hours without any problems surfacing. To be on the safe side, the bias pots were replaced on both channels as they can sometimes become intermittent with age. We did this as a precaution, since we could not find an operational issue. The PCB shown in the photo is perfectly fine. There is nothing wrong with it. The capacitors are NOT LEAKING. This is residual adhesive that we use on all capacitors on with case diameters larger than 10mm for stability and protection from vibration when shipping. Not pretty, but not defective in any way. There is nothing to repair or replace on "the little board". Put it back where it belongs and enjoy... and stop taking the amplifier apart for nothing!  Next... Big Dan |

As I said, I am no electrical engineer. To be on the safe side, I would have replaced/repaired the board. I will be pleased to be proven wrong when the unit is back in service. |

If there had been a need to, it would have been repaired or replaced.

Is there any interest in taking the ERC-3 CD Player up a notch and adding a hard drive, USB & network to it, making it a streaming, hi-end music source?
