One more thing, forgot to ask about physical size of this SMD components?
Cheers,
The SMD size code is 1205.

Nichicon Muse for 100uF starts at 10mm diameter. You can probably fit 8mm caps, but 10mm is really pushing it. Audio caps don't really have any special qualities, save your money and use something equivalent to the originals (and from what I see, Nichicon is phasing out all of their audio capacitors series). The UCC KME caps have around 140mA ripple rating and 2.5 Ohms (@120hz, not 1khz). Find something similar.
edit:I tested the NCC KME series capacitors, they show 1.42Ohms at 120Hz (the datasheet specifies 2.321 "Maximum ESR (Ω) at 20C,120Hz"). I'm replacing them with Nichicon PM which is 0.660mOhm @ 120Hz.
edit 2: Job done.

Bare card:

The instructions are as follows:
1) Lay electrolytic capacitor C70 6.3mm x 11mm 25V 100uF in a horizontal position to create clearance for the wavetable board
2) Bridge resistor positions R29 and R34 as shown with wire, or install SMD (1205 size) 0 Ohm resistors
3) Clear soldered wavetable pads and install header. I used a manual pump and a soldering iron at around 330c, and clearing the pads went very easy. The solder is leaded and is sucked away easily.
The card is working perfectly with the wavetable. As was mentioned, make sure you set a number to the "/a" parameter with ESSVOL.EXE (I use "/a 14").
