Re: [PolySix] Replacing NiCD - on Trident and Kawai SX210

Yes.  See as follows:

  Remove dead cell:

  Remove R29:

  Remove C27:

  Get some new parts:

  Solder the diode and socket in, and pop in the coin cell:

  The diode's band (cathode) should connect to the other diode's cathode 
when mounted in the R29 position correctly.

  I should really write the repair procedure for these pictures someday as 
I took them like 5 years ago...
