Definitely. Although I see myself picking up an end-game-ish (for my needs) amp like a MC302, or dual mono MC275s sometime in the future, I plan to fully upgrade both my vintage amps.
Both came from single owner homes, and were just sold b/c the 70 year old dudes were simplifying their lives. I feel a responsibility to keep the amps singing, pass them to down my 8-year old son one day, after college! For that environment, he can take my blastin' Behringer PA speaker I use for backyard movies.
