Looks Great

I purchased two of these. They both look great. The build quality is exceptional. It was a little finicky to put the first chassis together, but the second one was pretty easy as I knew what I was doing.

Note that the back panel comes pre-cut for the DIYAS chassis kit.

So sad the handles have been discontinued

Took longer than expected to arrive. The pandemic has obviously impacted the supply chain. The chassis is very high quality and worth the wait.

High quality

I ordered the chassis with Milled Handles unfortunately the handles have been discontinued. I was given a refund for the handles. The chassis is very high quality and makes the build a pleasure. I just need to find a compatible set of handles to match my other existing amplifier.

DELUXE 4U STEEL : A great enclosure/Chassis

This is a great a great enclosure/chassis. It is well designed and produced. I built Papa's F6 amp with this enclosure. And this enclosure made my project easy and fun. It looks great too! Initially, I set a low budget for enclosure. But I am glad that I changed my mind and purchased this. It was a game changer for me.


This is a great enclosure. Initially, I set a low budget for an enclosure. But I really am happy that I changed my mind. It is well designed and it looks fantastic. Assembling this enclosure was really easy. This enclosure cased Papa's F6 amp which is another great product. And it made my project much easier and therefore fun. In fact, it was a game changer for me. Well worth the price.

4 unit steel chassis

Great chassis, easy to work with. Maybe a little expensive but worth it for ease of building. Somewhat still a beginner but complete the F6 without issue and the chassis works great for it.
