I have recently come near to completing a rebuild of a pair of Quad ESL57s. More pictures to come soon but the following pretty much sums up the experience of working on these things :D

What will you do with the rectifiers? I rebuilt (and re-potted) mine about thirty five years ago, but I'm sure there are better modern options.
Excellent stuff Will. Been there, a bit fiddly at times isn't it.
Tip: Don't use a portable gas powered iron neat the dust covers as the exhaust gas can melt it :doh:
It's actually the dust cover though if you aren't familiar with ESL57 internals you'd be forgiven for thinking it was diaphragm material - each panel in ESL57 has a tensioned cover over each front and rear stator - the sheen is grey spray paint so the panels appear less visible though the grilles - though most don't bother reapplying this.
A very interesting project - looking forward to the next set of photos.
Will, what diaphragm coating are you going to use?
Hi Andrew
Luckily the bass panels didn't require stripping down to the stator level so they have the factory coating (some kind of nylon I believe!) :)
The treble panels had a problem so will likely be replaced with refurbished ones - unfortunately I do not have the time to rebuild the existing treble panels.
More pics to come soon!
