I have a 34yr old Carver M1.5t Amp thats not working. (And hasn't for years). Its mated to a Carver CT-7 into KEF 104/2 loudspeakers. All is about the same age. I've reviewed your process for bringing my Amp back to life and even making it more efficient. Wonder of the KEF's will be able to withstand the new power ?
My Amp was purchased by me from the Army Exchange in Hawai'i about 1987 when I was in the Navy. Honolulu Audio had it for $999, The Army Exchange was $650 with no tax. I bought it just after it was mislabeled and placed on the "Clearance Rack" for $1
