Antek Dynaco Mark III-Compatible Tube Amp Chassis

This item will be available in late Dec. 2026

   This upgraded Mark III-compatible tube amplifier chassis is constructed from heavy-duty 0.08-inch-thick aluminum with a durable anodized finish, offering excellent structural rigidity, long-lasting durability, and a clean, professional appearance. The solid aluminum construction provides a sturdy platform for supporting the transformers, tube sockets, and other amplifier components.

 The chassis features precision-punched openings based on the original Dynaco Mark III layout for mounting the power transformer, output transformer, choke, and tube sockets. The rear panel includes openings for the power switch, AC power inlet, and audio connections, providing a practical layout for a modernized Mark III-style monoblock amplifier.

 Designed for maximum compatibility, the chassis accommodates original Dynaco Mark III amplifier PCBs as well as compatible third-party replacement PCBs that follow the standard Mark III mounting layout. This allows builders to use their preferred circuit boards without modifying the chassis. It is also suitable for custom circuit designs that follow the original component arrangement.

 The anodized aluminum surface provides a durable, attractive finish that complements both vintage-style and modern tube amplifier designs. Carefully punched openings and a consistent chassis layout help simplify assembly and component installation.

 Ideal for DIY amplifier builds, restoration projects, and custom tube amplifier designs, this chassis combines the classic Mark III layout with durable aluminum construction and modern manufacturing. It offers tube amplifier enthusiasts a convenient way to build or upgrade a Mark III-compatible monoblock amplifier while retaining the flexibility to choose their own electronic components.
