My RevC project update (with pictures)

[orthoefer]

Here are some pictures of my RevC amps in progress. The cases began life as 8" x 8" x 3.5" Lansing B type gray boxes. I am waiting on some insert plates for the backs of the enclosures to arrive from Front Panel Express, so I haven't drilled/cutout the holes for all of the connectors. The extra aluminum stock came from Metals Depot.com, but it required a fair amount of machining. Allen head stainless machine screws came from BoltDepot.com. Front panel LEDs and Qualtek power entry modules are from Mouser. Vampire binding posts, input RCA connectors and hookup wire are from Percy Audio. Case feet are EAR MF-1010 also available from Percy Audio. Transformers are Plitron 24V 300VA toroids (077160201)

The amps are not finished, and I will post pictures as they are completed. Thanks for viewing. Here's what I have so far:









This is the Heatsink / board carrier which is tapped so that it can be bolted to the backplate of each amplifier:







This is the Front Panel Express plate on order that fits in the recess on the Lansing enclosures back panel:

did they do the side plates for you? would that ac jack be like this one?

thought about gettting one since it is $4.50.

what are the 2 extra holes for on the the L that holds the amp?

looking sharp!

Thanks.

The vented side plates are an option from Lansing. The slots are burr free and edges are fully anodized.

The Corcom AC jack you found is different from mine. Mine has a built in switch, fuse, and voltage selection (120 or 240 VAC). The Corcom is a nice unit too.

The holes in back of the L bracket are how the whole bracket mounts to the amplifier case. See the picture of the back of the amplifier below. This picture shows the back of the amp without the holes for the binding posts, RCA connectors, and power entry module. I am waiting to drill/cut these holes until my FPE plates are delivered. This way the holes are located properly.

Wow what an awesome job! I like the plan for the panels, and the way you are mounting the REVC to the case. I will watch very closely for the finished product.

Cheers!

And i thought i went overboard by spending $40 for my goldcolored pre anodized enclosure from Par-Metal.....

Congratulations, by the way what transformer did you use?

The Front Panel Express plates arrived. Everything fits perfectly--not bad for working off data sheets alone. You can get an idea of how things will go together from the photos below. The amp chassis must be milled with through holes for the parts to fit first. This overlay method means that the parts are indexed off the CNC machined panels, so my hand milling doesn't have to be perfect.

how much total for the chasis with the binding posts and what not?

[orthoefer]

I haven't calculated my cost for the project, but I am sure it is not insignificant. Bundled into the cost for me is a tap and die set, non-ferrous blade for the table saw, and more tools. This project was more of an exploration of my abilities. Plus, I wanted to learn more about circuit design and soldering technique.

Here are photos of the finished project:

Very Nice!!!

What an awesome piece of work ! Why do you use AC filter? Have you tested it yet? In the past, I got terrible result with it. The dynamic was very bad.
