I decided to try and do a recap of my office M33s based on the improvement I got with the DSP5000s. Below is a breakdown of the parts to service a single M33 (don't forget to double quantities for a pair). Before buying the components I would suggest opening the backs and checking the component values.

     Board   Qty Ea  Value           Manufacturer Part No

     Amp     2       1000uF 16V      Nichicon     UFG1C102MHM
             5       10uF 50V        Nichicon     UFG1H100MDM
             2       100uF 35V       Nichicon     UFG1V101MPM
             4       470uF 16V       Nichicon     UFG1C471MPM
             2       4700uF 35V      Nichicon     UKW1V472MHD
             2       3.3uF 400V      Ansar        Supersound

The two 1000uF 16V capacitors are a larger physical size than the originals, but they do fit with a bit of a squeeze. You will also need some thermal grease to put between the heatsink and the chassis upon reassembly.

This may also be applicable to DSP33s
