Laney Lionheart L20H

Valves for Laney Lionheart L20H amplifier.

The Laney Lionheart L20H amplifier uses:

  • 2 x ECC83 (also known as 12AX7) preamp valves.
  • 1 x Balanced ECC83 for the phase splitter position (V3).
  • 4 x  EL84 matched power valves/power tubes.

The Laney Lionheart L20H is cathode biased so you do not need to rebias when you change your power valves.

Over time your valves will lose their tone and their power. After a while, you will start to get a variety of crackles, hisses and other odd noises before the valves pack up altogether.

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

We always recommend Sovtek or JJ valves for the Laney Lionheart L20H amplifier. This is because they guarantee you get awesome tone and long life and they don’t cost a fortune.
