Hope this turns out to be useful to someone out there. This should work for any other device that uses this particular adapter.

The coated mounting plate is rigid and durable, while the new hatched clamp design offers flexible adjustment for maximum playing comfort. Stability and durability have been improved over the previous-generation PDS-10, with larger rubber feet and doubled-braced steel legs that are 33-percent thicker. I was not able to locate a female coax connector to wire up an extension cable, nor did I want to put an extension cord and have the wallwart mounted on the rack. The PDS-20 provides a rock-solid foundation while performing with your Roland SPD-series percussion pad or HandSonic percussion instrument.

The electronics are fat, full and kickin', and the acoustic sounds are so authentic you could close your eyes and think you were hearing the real deal. My SPD-20 is mounted on the left side of my rack, the power strip where everything's plugged in is near the rear right tube. The SPD-20 percussion pad delievers 540 strikingly realistic percussion sounds, from acoustic drum kits to electronic sounds to world percussion instruments.

In case anyone was wondering, nothing's wrong with my original adapter I just needed a (much) longer cord than the 6' that is supplied with the Roland adapter. Regrettably, while MCM carries a rather large selection of replacement DC adapters they do not carry any AC units that I could spot from the last major catalog.

The coax power plug is one of the more common types to fit answering machines, etc so you'll need to either wire up an adapter cord with the MCM plug on one end (my recommendation), or hack off the plug and solder the MCM plug right on to the wire. It is part number 273-1631 and is a switchable voltage unit. While Radio Shack does not carry the plug, they do carry at least one AC adapter that appears to fit the voltage requirements.

The cost is less than $1, so the expense of a replacement power supply plus the possible labor of soldering this up to make it work will easily dwarf the plug.

It is 3mm on the inside, 6.3mm on the outside, part number 27-860. However, I was finally able to obtain a suitable replacement from MCM Electronics. The dimensions of the coaxial barrel power plug are rather large and difficult to locate. Any higher amp rating will work as long as the voltage is AC, not DC. For those of you who might have a need someday to replace the wall-wart transformer for your SPD-20 (or presumably your SPD-11), here's the specs to match the BOSS BRA-120 unit:
