Welcome to the Cubes for Tubes Online Shop

We have only very few transformer covers left in stock. We chose a retro-like wrinkle finish for the new covers. Since we don’t want to offer both types at the same time, we will clear the stock first. We apologize for the inconvenience. New covers will be available soon. Please send us an email if you need further information.

Cubesfortubes.de offers a variety of transformer covers for your DIY tube amp. Feel free to visit our special offers page. Sometimes we can offer transformer covers at reduced prices.
