Marshall Tremolo 50w head

Best valves for Marshall Tremolo 50w head

The Marshall Tremolo 50w (1987T JMP Plexi) amplifier uses:

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

Note: The balanced ECC83 goes in the V3 position which is the preamp valve furthest from your input jack. Looking from the back it is the third preamp valve in the line of three and it sits next to the power valves. The single ECC83 on its own and to the right of the power valves is for the tremolo.

A brand new set of valves will get your amp sounding better than ever. W can supply you with either Marshall branded EL34 or JJ Electronic EL34 power valves.

About the amp

We have to be careful with this amp as it is easily confused with the Blues Breaker and Blues Breaker reissues, none of which used EL34s. We strongly recommend that you remove the back of your amp and check what valves are inside.
