Thanks dpstjp (and admin) for the welcome and especially for the quick response to help, appreciated.

It certainly reminds me of Dave Hall at Meridian, now that guy was fast and a real gentleman too. It certainly seems like the guys here are like that too.Thanks in advance for all the kind assistance and help I will be receiving.

Hopefully I will be able to contribute in some meaningful way in the future.

PROBLEM NO.2 :

I fitted the DAC boards and left the music on overnight, listened for a few minutes earlier and noticed that on one of the speakers both bass drivers were not producing any sound, the tops and mids yes.

I removed the board and put back the old one and all the drivers perform well.The "red capped" works perfectly, the "blue capped" one does not.

I took a pic of the two boards and notice that they are the same, but different. Any advice/comments?
