This Marshall DSL15 superior valve kit has 4 Tung Sol 12AX7 and two Tung Sol 6V6GT’s Marshall today use Tung Sol in their current production of new amps.
Tung Sol offer a superb punchy tone that is just made for Marshalls. The Tung Sol 12AX7 has a spiral wound heater which minimises hum. Nazareth will only use Tung Sols from us in their JCM900’s because the sheer soundstage presence of their amps are the best they have ever heard
These are the best 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
