The Marshall JTM 30 amplifier uses 2 x ECC83 (also called 12AX7) preamp valves, 1 x Balanced ECC83 for the phase splitter position (V3) and 2 x 5881 matched power valves.
Over the years we have noticed that quite a few owners also have 2 x EL34 matched power valves instead so before you order, have a quick look inside your amp to check.
Over time your valves will lose their tone and their power. A brand new set of valves will get your amp sounding like new again. We always recommend JJ valves for the Marshall JTM30 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 valve manufacturers in the world. So don’t pay higher prices for valves from the same factory that have simply been rebranded by other companies.
So restore the tone, the power and the sparkle to your guitar amplifier. Treat yourself to a brand new set of valves today.
