We always recommend JJ valves for this amplifier. This is because they guarantee you get awesome tone and long life and they don’t cost a fortune. Remember, JJ is one of only five manufacturers of valves in the world. So don’t pay higher prices for valves from the same factory that have simply been rebranded by other companies.
