The most common problems with the electrostatic panel on DM 70’s is loss of output due to splits occurring in the diaphragm, arcing damage causing polarising voltage leakage (EHT) and accidental damage.

It is an easy task to replace the diaphragms on these speakers, re-coat them and repair the damage caused by over enthusiastic use of the volume control (arcing or sparking between stators)!

This will bring the performance of the ESL panel back to “as new”.

Generally, the electronics in these speakers are quite robust and rarely give trouble, the most common problem being failure of the EHT supply components. If this is suspected, feel free to contact us to receive troubleshooting advice.

The kit contains sufficient diaphragm film and conductive coating to replace the diaphragms many times and comes with all components and adhesives likely to be needed, plus full instructions.

Some speakers may have had “bodgy” repair attempts in the past and could have had the air gap spacers damaged during attempts to remove the original adhesive. If you have damaged or broken air gap spacers, there is now no need to be concerned, we are able to supply replacements.

Full set of replacement air gap spacers    AUD $112.00
