Default My Babelfish J Monoblock Project

A little over a year ago I started building a pair of amps based on Zen Modís Babelfish J boards. These amps were built to install into my console project so the case was a pair of used telecommunication boxes since they wouldnít be visible. Ugliest amps ever;

After I decided that I was never going to be happy with the sound from a smaller speaker cabinet I remodeled the cabinet and deleted the speaker/amp areas on each end. I love the cabinet in its new form, and I love the performance of the amps, so new proper cases are the order of the day.

I used 5 of the China/ebay Pass Lab look a like heatsinks per amp. But for the rebuild Iím upping to 6 per amp.

I originally started down the road of building typical Class A case, 3 sinks down each side, all aluminum case. But it takes up so much floor space, so looking to stay vertical. In my first F5 build I had heat sinks stacked on top of each other and lots of criticism over the effectiveness. But my amps now, have less than 2 degrees Celsius difference between the top row and the bottom row. Maybe the gap between and minimum connectivity between helps?

Anyway, I ordered up some double milled Medex and went to work. Since I have access to such serious woodworking equipment I just have to take advantage. Some of the cabinet makers there have become friends and enjoy discussing HiFi and help teach me tricks. After I cut and mitered the perimeter frame I laid all the pieces together in a straight line as they would be attached. Put tape tight across the miter, carefully roll everything over, keeping in a straight line, then spread the glue. Then start at the end and raise the first piece closing the miter and keep going. Tape the last corner, spread glue to the perimeter miter and drop on the back panel.

If everything is cut right, you end up with this and no nails or fasteners.

The shop has every machine, CNC, paintbooth, etc. I have free rein on weekends unless the shop has a project they need to work overtime for.

I bought the heat sinks from eBay here 263262235520.

To shield the Medex some from the heat in the cabinet I lined it with laminate.

The cabinet and the front panel sprayed with the first round of primer

I ordered back panels from Panel Express. Then set up to recess it.

And today I received the nameplate for the front. If everything goes well I will spray out with finish this weekend and start the rebuild.

Thanks for the positive comments guys!

I had routed the front panels before the front faceplate arrived, hopeing that front panel express was consistent in making what you order exactly. They didnít disappoint. Will look better in black though!

Back panels have some new parts, some parts will come over from the amps. Also proper support and feet.
