Pizzolato Amplifiers - Universal Chassis STANDARD
This is our very own universal tube amp chassis design.
Note: The standard option doesn't include any hardware besides the four screws to secure the lid.
We thought about every single detail to make it as easy as possible for both beginners and experienced amplifier builders, to put together an audio amplifier.
Our exclusive design can be used for not only guitar/bass amplifiers but also hi-fi and other projects.
It is pre-drilled for the most common jacks, potentiometers, switches, tube sockets, fuses, power
connector and a variety of power and output transformers.
The possibilities are endless with this chassis.
You can easily wire circuits that use:
- up to 4 noval tubes, 2 octal/noval* power tubes and 1 octal rectifier
- up to 5 noval tubes and 2 octal/noval* power tubes
As the chassis is made of aluminum you can easily drill more or enlarge existing holes.
Check the additional info section for more detailed information on direct drop-in transformers and available holes.
