I've owned three different Walter Woods Amplifiers, a original MI-100-0 from October of 1970, a MI-400-8 from 1992 that I sold on TB, and a early Electroacoustic Ultra that I still own.

They're incredible amplifiers, great tone, longevity, and durability. Unfortunately, they're difficult to repair because Walter never published schematics. Walter can repair most of them,

but as time moves on some of the older models just can't be repaired. An example would be the MI-225-8 because it has two analog power amplifiers running off a single SMPS that

Walter is unable to built anymore.

:thumbsup: Thank you very much for your reminding:thumbsup:

God bless my WW will not break, even though it is still very new I also know that it can hardly be repaired, especially in China. For example, one of the two blue lights of my Aguilar AG500 has gone out, but it is still driving normally. I can still accept it because I think I still like a / b amp. Finally, I decided to sell Epifani Piccolo 600, Aguilar AG700 and TC rh750.
 
Yes, one was better for upright. The EQ circuits were different. I wonder which circuit Walter used in the single channel amps.

To my ear the Electracoustic sounds brighter overall and I have to dial down the high mids more.
I only found that the high frequency through WW is more "clear and powerful", and it has not reached the range I can't bear. I've tried the bass of ash + Maple FB,It's true that there will be a brighter and sharper high frequency, but I can deal with it by moderately attenuating the tone and high frequency on the bass. Maybe it's because of different pickup types, or wood and preamp?
