I have a private email asking
Where did you send your 2905. I have 3 of 4 crackling ? mylar repair?? I live in MInnesota.
I cannot reply to private emails on Audiogon, so my answer must be public.
I pull the panels out myself, which requires some mechanical and soldering skills. I then send them to John Hall who lives near Melbourne Australia. He gives a five year warranty on panel repairs and charges about A$300 per panel.
I used to try to identify which panel had become faulty, and get them fixed one at a time. I think I can pull a 2905 apart in my sleep. The reality is the glue used was defective and all panels fail at about the same time after 10 years. John reckons you might as well repair all the panels at the same time and I now agree with him. The last 3 of my 12 panels are currently being repaired.
I did try to repair panels myself, but could not find a way to coat the mylar with the required slightly conductive film.
Obviously the panels are much lighter than the entire speaker so it may be viable to send them to the antipodes for repair. Not sure if John wants extra work though ...
