This "Prelude Percussion Module" drum sound and surface pad was an interesting find on eBay. A cheaper alternative to the Simmons and Linn drums at the time with an interesting eprom port to upgrade the sounds. Trouble is these factory sounds are increasingly rare and difficult to get hold of.
If you have any eprom sounds for this that you would like to share or swap then contact me.

You can shop around for an equivilent. Obviously the Size and Voltage are critical, but also pay special attention to Airflow to ensure provides enough cooling and Current rating to avoid overloading your mixer power supply! Also worth comparing noise levels as can be possible to find 18dBA models - still not whisper quiet but improvement on the original
If you don't find an alternative that also has the right connector or long enough leads there is option to cut the connector off your existing fan and join to your new one.
