Marshall Super Lead 100w

Best valves for Marshall Super Lead 100w amplifiers

The Marshall Super Lead 100w amplifier uses:

• 2 x ECC83 preamp valves (also called 12AX7).
• 1 x Balanced ECC83 for the phase inverter (in position V3).
• 4 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.

Early versions of this amp (1959-1967) were fitted with 4 x KT77 power valves. After 1967 Marshall changed these for EL34 power valves. In the 1970s, Marshall had problems with the EL34 valves breaking in transit so they started shipping many overseas models with 6550 power tubes instead. So it’s very important that you check what is inside your amp before placing an order.

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