Checking the Pre-Assembly of Enclosure.

Any suggestions for my next built are welcomed.

I got samwha 15000uf, 50v for Rs.150 in kochi. Working fine

Do they have 22000uf 35 or 50v caps where you got it? I am looking for them at reasonable cost and finding genuine Samwha is quite a task

Thanks

Call them. like most indian stores, stock positions online have little semblance of reality.

Sadik, looking gorgeous! Fantastic workmanship.
My only suggestion is to change the front panel bolts to black colored ones for a seamless stealth mode front look.

Thank You. I will change them to black.

Looks good Sadik, way to go very professional work. What are the exact dimensions of this chassis? I think you came up with this design based on your heat sinks! It does not look like the usual 430x150x300 or 430x150x350 that you get for power amplifier cabinets.

Thanks for the comment. Yes this is custom size designed as per size of heat sinks. The dimensions are as below.
Outside : 515 mm Width x 308 mm Deep x 240 mm Height
Inside : 350 mm Width x 290 mm Deep x 234 mm Height
Face Plate Dimension : 515 mm Width x 250 mm Height x 12 mm thick.

I will share the placement layout as the progress goes on.

The most prominent and the most essential part in a Class-A amp is the heatsink. So why hide them partly behind a huge front panel.

Perhaps for your next design, you could think of making the front panel very small and "display" the heatsinks more. Maybe handles could also be put on them -- a convenience factor too, I think!
Just a suggestion...

I am still on search for Ready made Handles (good looking and good finish) available locally.

Regarding Front Plate, It will not look aesthetically good if the front plate is shorter then the overall width of Enclosure.

Great job Sadik!

Try some all aluminium door kind handles which actually look good without any coloration and design. Pure simple and plain ones will look good and also should not cost more than 500 bucks for a pair locally in your home utilities hardware stores. You can even try the SS ones if you prefer

great going Sadik!
and happy to know that your going ahead with the simple and clean power supply - as they say there is no replacement for displacement

can't wait to see the finished product!

Drilling, Tapping and Anodizing is pending. They will be Silver Anodized.

Edit:
Size is 50 mm Diameter x 18 mm Total Height

Getting the job ready for anodizing.

Those feet look gorgeous Sadik

You are actually a true DIY guy in the forum where every item is being made rather than just buy off the shelf like what I do and then assemble. Hats off to your passion
