This Marshall DSL15 quality valve kit has four EH 12AX7 and two EH 6V6GT’s
Why buy this kit?
The EH 12AX7 has a spiral wound heater which minimises hum.
These are good quality of the Russian valve offerings..We use our SUPERMATCH process to match one of the the 12Ax7’s and the 6V6GT’s. We supply a test certificate showing the matching test results. The hand matched 12AX7 should be placed in the phase splitter position next to the 6V6GT output valves.
Mae sure the bias is set on the output valves to ensure they have the best sound and do not overheat too. Overheating shortened their life. We enclose a leaflet with the kit with recommended bias settings.
We test your valves on our suite of AVO testers
