Hot Rox UK - KT66 Branded Valve

In search of the ultimate KT66, premium matched onsite at an affordable price.

Replicated British KT66 giving Plexi Marshall and JTM45 tones at a price that is affordable.  We have searched for high standards in our forever-increasing and vulnerable valve market to give our customers what they need, what is affordable and an acceptable price to pay.

The Hot Rox KT66 can also replace the 6L6 type valve (please check your bias when replacing output valves).  Quad II amplifiers will also benefit from the Hot Rox KT66.

We at Hot Rox UK are in search of high-grade vacuum tubes at affordable prices. Not just great valves, but affordable valves too. We owe this to our loyal customers for the years they have supported us.  We are working for you so you can enjoy and play the music you love that gives life to our souls. 'If music is the food of life, then play on'
