Sovtek 12AX7LPS Long Plate Preamp Valve
From £29.42

Sovtek 12AX7LPS is a long plated version of the 12AX7/ECC83, favoured by many amp manufacturers for its smooth, rich tone. Not recommended for the V1 position in combo amps because long plate 12AX7/ECC83S types are more prone to microphonics. We also have a balanced option for phase splitter applications.

From £26.20

JJ 6V6S valves, available here as singles, matched pairs and matched quads. We test at voltages seen in your amp. The JJ 6V6S can withstand higher volts than most other brands of 6V6.
