It is a lovely amplifier, I owned on for nearly 25 Years and then purchased the MI-400-8 which I owned until very recently. Understand, that the seller is asking the price that Walter charged for a new amp
circa 1977. I still have my Woods Electroacoustic Ultra. (blue light) Even based on what I know about Walter's amplifiers with their longevity and reliability, purchasing a 20 year old amplifier that only one
person can service isn't an ideal situation, especially if it's going to be your main amp. My personal experiences with Walter have all been great, but the cost of getting one repaired keeps going up.
For my last service on the Electroacoustic, Walter charged me $500.00 including return shipping, to clean the circuit board. While it corrected the issue, if you were to need a MI-100-8 repaired, having
that done will cost you nearly as much as you payed for that particular amplifier. Just my take. I just wanted to provide my perspective on purchasing a 25 year old Walter Woods.
