Hi All,
Thanks for your interest and help. To answer your questions:
Plato: I checked the continuity of the fuse and it was OK.
Rmrobinson1957: The problem is from both of the speakers. They were connected to a quad 33/303 pre/power amp and I always thought that the poor sound was because the amp under powered (45 WPC)and could not drive the electrstatic panels. I have just upgraded to a Primare A30.1 and the complete lack of mid range and treble was unchanged with the upgrade.
willhitx: Sorry for the confusion. I am not sure of the correct terminology. by the elctrostatic posts I am referring to the speaker input connections to the electrostatic panel.
I have also checked that the AC supply was reaching the internals (it is) but when doing this I noticed that there is a red LED on the printed circuit board which illiminates for about 30 seconds and then goes out. I am not sure if this is normal. I have had other feedback which suggests that the panels are only good for about 8 years and then need replacing and so far this seems to be the most likely cause. I have lodged a call to ML service department for their advise.
Regards
Paul
