Best valves for Mesa Boogie Simul-Class 2:Ninety 

The Mesa Boogie Simul-Class 2:Ninety amplifier uses:

  • 2 x ECC83 preamp valves (also called 12AX7).
  • 1 x Balanced ECC83 for the phase inverter (in position V3).
  • 8 x 6L6GC matched power valves/power tubes.

 Note: The balanced ECC83/12AX7 goes in the V3 position which is the preamp valve furthest from your input jack.

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

We 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. The power valves are a direct replacement for the Mesa STR440 tubes and they are bias selected so there is no need to re-bias your amp.

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.
