CC-711B Tube Amp Chassis 300B

Mono Tube Amplifier Chassis for 300B 

We are pleased to introduce our new Mono Tube Amplifier Chassis, designed for high-quality DIY tube amplifier projects. Constructed from heavy-duty 0.05" thick steel, the chassis provides excellent rigidity, durability, and resistance to vibration, helping to minimize mechanical hum and unwanted interference.

The chassis features precision pre-punched mounting holes for tube sockets, RCA input jacks, and speaker connectors. Dedicated mounting locations are also provided for our toroidal power transformers and output transformers, making assembly clean, accurate, and straightforward.

For safe and reliable operation, the chassis includes a high-quality IEC power inlet with an integrated RFI/EMI filter, fuse holder, and power switch, helping to reduce power-line noise and interference.

A CA-series transformer cover is included, providing a clean, professional appearance while offering additional shielding for the transformer.

The main amplifier PCB is also included, with mounting holes precisely aligned with the chassis for easy installation. No chassis modification or additional drilling is required.

This new mono chassis provides a solid foundation for building a high-performance tube amplifier with a professional appearance and convenient assembly.
