Description

The Deluxe Chassis is the ultimate DIY Amplifier playground.  We don't know of another chassis for sale in the world that makes life as easy for DIY Audio enthusiasts.  Packed with features so you can focus on having a good time building your amp instead of getting roadblocked by the hardest parts of custom machining.

Introducing the 4U "Jack of all Chassis"...

Heatsinks

Faceplate

  • 1 x aluminum faceplate 10mm thick, 450mm wide with rounded corners and anodized in silver
  • The silver front panel only (not the black), has the following additional features:
    • 9 blind M3 pre-tapped mounting holes suitable for mounting all kinds of things to the faceplate - diodes, PCBs, riser panels, potentiometers, etc
    • Mount single or dual PSU boards directly to the back of the front panel
    • Designed so risers can be bolted to the chassis using two axis to create stable interior platforms within the chassis and maximize all the interior space 
    • Use with risers and easily mount front panel components such as pots and dials to the risers with extension rods going through the front panel, saving the need for complicated or messy hacking in order to attach things to the front panel 
    • The 9th hole is perfectly centered in the chassis and approximately 1/3 of the way down from the top (or bottom - you can spin the front 180') and can be used either as a mounting hole or as LED pilot hole

Back Panel

  • 1 x aluminum back panel 3mm thick and CNC routed to our back panel specification, ready to accept your choice of PEM, RCAs and premium binding posts or drop our back panel parts kit (not included) straight in
  • It has Neutrik XLR compatible holes on the back to accept XLR, XLR/1/4" combo or RCA-in-XLR-format connector so you can easily connect XLR, 1/4" or RCA cables to your amplifier
  • Please see the 4U Back Panel Specification for more details

Covers

  • 2 x aluminum top/bottom covers, maximally vented with 6 rows of venting strips, to provide an ideal balance between airflow and stiffness

Baseplate

  • 1 x galvanized steel, perforated inner baseplate 300mm deep and 1.5mm thick which is pre-drilled with a pattern of holes allowing for easy mounting as well as less flex
  • All holes in the base are in a DIY friendly 10mm x 10mm hole pattern.  This makes it easy to design the mounting for anything you might want to attach, as well as ensuring if you rotate it 90 degrees, it will also mount perfectly.
  • Holes are aligned so there is a column of holes directly in the center to make it easy to drill out a hole for perfectly centered transformer mounting
  • All diyAudio PCBs going forward will come with mounting holes spaced apart in multiples of 10mm to allow for easy mounting in any orientation
  • Riser Panels can be combined with the 10x10 pattern to create unlimited horizontal and vertical mounting configurations

Riser Panel Compatible

  • We've created riser panels that can be bolted to the base, front panel or each other to create unlimited possibilities for the maximisation of the internal space within the chassis.  
  • Want to stick burning amp output boards, bias boards, gain stage, dual psus, dual transformers, soft start and speaker protector all in a 4U chassis? Walls and shelves now simply screw together in any configuration to dramatically increase your ability to optimize the internal space.

    4U Deluxe F5 plus handles

    Chassis was a little expensive but if your doing an F5 you probably don't want to go smaller. Assembly was easy and the chassis look great and it's pretty much made for the Diyaudio boards. Rear panel has no center support and while it seams thick enough pushing on it too hard while inserting a power cord will bow it in so think about adding a brace. The predrilled front panel made mounting the handles easy. When assembled one of the handle bars was loose and the other fine so it may need a little shimming. That said I'm actually pretty happy with the chassis and would purchase again. Chassis arrived in California in 5 or 6 days.

    Great chassis and easy to build

    I built the Pass DIY Sony VFET amp kit with this chassis and it turned out very nicely with drilling countersunk holes for the faceplate mounting screws and the two LEDs.

    M2X

    I bought the 4U along with the M2X boards and built the M2X. Great enclosure, heat sinks drilled and tapped for boards and MOSFETs. Amplifier is dead quiet using this enclosure, made building the amp so easy, not so big to be difficult to lift and move around.

    Quality

    Great product, quality material and build. Only had one pre-tapped hole on one of the heat sinks that wasn't done quite right and has white burn marks around it and doesn't accept much thread, have to buy tools and re-tap it in order to use it.
    Otherwise A+
