Hi WW owners!
I have my eye on a MI 225, and am wondering if that is the amp that Walter said he can't repair anymore? I read a post somewhere here where that was mentioned. I've never owned a Woods before, and I know the repair situation with Walter is iffy anyway. Anyone have this amp? Is the 300 watts at 4 ohms creating enough volume with a 4 ohm cab?

I used to own one and sold it when I was able to get a newer Electrocoustic MI-200. Apparently there is a component (or components) that can no longer be sourced. If that fails, the amp is toast. I'm not sure if he will work on it if something else is broken.

I used mine with a pair of Epifani 1-12 cabs and later a pair of 1-12 Bergantinos. Plenty of volume, even with a single cab. WW ratings tend to be very conservative. I'm pretty sure it's rated for more than 300W at 4 ohms.

Thanks, Brian. That was exactly what I needed to hear!

The MI-225 is unique in that it has two power amps ganged together, driven by a single power supply. There is an amp service in Germany that claims to have produced

schematics for every Walter Woods model and does repair work.

Interesting! I'm thinking I'd probably rather not send an amp to Berlin if I don't have to. I'll keep looking. Thanks, Ric!

Dylan,
Yeah, I get that. What's interesting to me is that technicians in Berlin can "apparently' fix something
that Walter Woods can't repair himself. Maybe they have a source or stash of components that Walter
doesn't. Hard to say.

What was the part? There is a single channel 225 for sale right now. Would that have the same issue or is it something having to do with the stereo power amps?

Dylan,
You'd have to speak or write to Walter. My understanding is that the MI-225 has two mono power amplifiers, driven by one SMPS power supply. There was a component or components involved in
the power distribution from the digital power supply to the independent power amps. Only Walter would have any idea what the issue is. I don't think it would matter if it were the stereo version
or the mono version.
