Need info on MIDIVERB2 power adaptor..

[David Lee]

My MIDIVERB2 has gone south on me do to a failed factory 9v power supply. I
was hoping someone has one of these units and could tell me the following:

1. Is the + power lead on the tip or the ring of the 2.1mm power connector?
2. What is the stock transformers current rating in mA?

I called Alesis to see about getting a factory replacement. They wan't
$19.99 for the adaptor for the MIDIVERB2. In looking into some of the DIY
catalogs I have and it becomes obvious that I could order an after market
supply for about $5 US.

Thanks
