According to the schematics sheet I have (from didier's site), the value
is 2u2. Unfortunately, there is no mention of the actual type of the case
(beside being radial).
As it seems to be part of an 107kHz low pass filter, I would assume
that most tantal capacitors and probably all ceramic capacitors that
fullfill the 35V spec are ok. As this is a heated part of the whole
circuit, i'd go for an capacitor that is rated for 35V at 100°C or higher.

Good candidates for capacitor manufacturers are Kemet and AVX
(higher quality than the cheaper manufacturers and still reasonably priced)
