All tubes sold or fitted by Sharp Sounds are tested and matched using an Amplitrex AT1000 digital tube tester. We will also test and match your tubes that you have purchased elsewhere. Just getting the tubes in your amp tested can have a massive impact on its operation. We can single out individual tubes that require replacement, saving you cash, time, and frustration!!
Tubes are consumables and as such are not covered by warranty unless otherwise specified, however tubes D.O.A. will be replaced. All tubes sold and/or fitted by Sharp Sounds are tested beforehand using an AMPLITREX ‘AT 1000’ digital tube tester.
