Best valves for Vox AC100 Mk2 amplifier

Vox AC100 MK2

Best valves for Vox AC100 MK2 amplifiers

The Vox AC100 Mk2 amplifier uses:

  • 1 x ECC83 preamp valve (also called 12AX7).
  • 1 x Balanced ECC83 for the phase inverter (in position V3).
  • 1 x ECC82 (12AU7).
  • 4 x EL34 matched power valves/power tubes.

Be very careful, if you have a Vox AC100/2 (a slightly different amp with an almost identical name) which was produced at the same time as the Mk 2 it uses an ECC82 in the phase inverter position not an ECC83. You will see that we have kits for both versions of this amplifier.

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 in the world. So don’t pay higher prices for valves from the same factory that have simply been rebranded by other companies.

About the amp

  • Produced between 1965 and 1968.
  • Vox went bust in early 1968 but production of this amp continued for another year or more under “new management”.
  • Single channel amp with two input jacks.
  • The AC100 MK2 has a bit more gain than the AC100/2 as a result of the higher gain preamp valve in the phase splitter position.
