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.

Transformer Covers in Stock

Which transformer cover do you need? A 80 mm transformer cover has a base that is 80 mm deep by 80 mm wide. The 100 mm transformer cover measures 100 mm by 100 mm etc. You can calculate the inside dimensions by subtracting 5 mm from each side. See the product descriptions for further information. You can quickly convert mm to inches by using our online calculator. It converts mm to inches or vice versa. Please note that you have to use a deicmal point. A decimal comma will be ignored.

Amplifier enclosure »The Pipe«

Unit price:68,50 EUR
(incl. 19,00% VAT plus shipping costs)
 
Product sold out
 

We designed “The Pipe” as an enclosure for active or passive preamps, small stereo power amplifiers or medium-power monoblocks. It is also excellent for external power supplies. This enclosure looks particularly good when several modules are placed side by side. And why not build a T-Amp in it as well? The entire internal assembly is secured with four screws through the equipment feet and can be removed as a single unit. This makes assembly, servicing and modifications a breeze. The enclosure is matte black powder-coated. The front and rear panels are made of brushed, anodized aluminum and can be further machined as required.

Exterior: 150 x 150 x 250 mm
Interior: 140 x 140 x 230 mm (Width x Height x Depth)
