Miss Melody ES688 – ESS AudioDrive 688 Capacitor Replacement

Recently I had the joy of being able to replace the capacitors on a Miss Melody ES688. The poor thing had NCK branded caps, which are way past their best before date. Installed some Panasonics and Rubycons and it’s ready to roll. Just need a machine to test it in.

Those old capacitors were way past their prime and couldn’t even be found on the big list of decent to lesser decent capacitors.

More information on this card can be found here and here. A good place to start looking for the drivers, if needed, is also here.
