The ENGL Metalmaster 20 amplifier uses 1 x ECC83 (also called 12AX7) preamp valve, 1 x Balanced ECC83 for the phase inverter (in position V2) and 2 x EL34 matched power valves/power tubes.
This amplifier is available as a head (E309) or as a combo (E304). Both amplifiers use the exact same valve set.
A brand new set of valves will get your amp sounding better than ever.
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.
So restore the tone, the power and the sparkle to your guitar amplifier. Treat yourself to a brand new set of valves today.
