Another 100W hifi amp

[Aniket]

Amp build complete, after a whole day playing with drill, jigsaw, screwing, soldering.
The amp's case looks ugly but sounds beautiful undoubtedly.

Cheers!!!

It only needs to please you.

But......the cable entry from the power plug is not your serious, right?

very nice amplifier

Thanks Sir.

What made you think that?

The power cable + plug + socket is rated at 250V-10A.

I can see what concerns you.

It does not concern Ani, since he does not care about whether the cable pulls out or cuts through.

What makes you think that too.
It is secured with a knot inside(glued) and a cable tie. I would also insert a rubber washer(didn't had in stock) for the cable to pass through.

I hope you have at least deburr the hole.

Better would this Cable gland

Yes I had(now out of stock in my parts bin) this kind of rubber washer that would fit in the hole and cable would pass through it.

Thanks anyways

I got the case made at a local sheet metal shop, made from 1.5mm steel sheet.

The fan is mounted in the back to exhaust hot air out. the space between heatsinks forms the passage for the air to pass, thereby cooling the heatsinks.

Care to share your PCB layout? thanks.... nice build...

Aniket, that layout looks awesome man I like it

I sure hope you can find a better and more practical way to secure the mains cable

but amp could still be nice though

Hi,
I agree to your safety concerns. I just did it for the time being as I didn't had the power connectors in stock.
I am going to buy a bunch of these(pics attached) on my next visit to the electronics market.

Aniket

chassis connector also gives good options for connecting fuse and switch inside

there are also special hard plastic grommets made for this
if that would be more 'convenient', and fit what you already have

Very good project. Must be easily repeatable. I like the one-side PCB layout with relatively short thick lines.

Congratulations and thanks for sharing!

Hi Aniket, I also bought that type of connector, I went with the one with built in switch and fuse, very convenient, you get one with mains filter too.
I just recycled a old power cord used on my old PC, for the power cord

Yep, it's also available here, even better option.

Thanks Vostro

I actually use even the "bigger" one - with the main power switch
