Best valves for Marshall JCM900 MKIII Hi Gain 2100 amplifier

The Marshall JCM900 MKIII Hi Gain 2100 and 2101 head and combo amplifiers use:

  • 2 x ECC83 preamp valves (also called 12AX7).
  • 1 x Balanced ECC83 for the phase inverter (in position V3).
  • 4 x EL34 matched power valves/power tubes.

We offer two superb valve kits for this amplifier.

You can choose between Marshall EL34 power valves or JJ EL34 power valves. If you currently have Marshall power valves in your amp and love the sound then the Marshall set is the one for you.

Many of our customers like the JJ power valves and so we also offer these as a set.

Please note that both sets use JJ preamp valves.

You can order these valves singly, the power valves as matched quads or a complete kit. However, we strongly urge you to change all your valves at the same time. It’s the cheapest way of getting your amp sounding its very best.

A brand new set of valves will get your amp sounding better than ever.
