: What year was the Sunn Model T born?
Mark;
I find the Model T in my 1974 Sunn catalog but not in the 1971 catalog. I'm missing the catalogs in between those years, so it could have appeared earlier. Pull your chassis and check the pot code on several of the pots. That will give you a rough idea....remember that the pots may have been manufactured a year or more in advance of the amp's construction.
