Vegematic1966! Have to say, John, that is one clean amp enclosure design. Minimal, i.e., only the essentials for that amp. Clean construction, attention to separation of signal and power, plus twisting associated wire for noise reduction. Well done. I do think I remember this amp from back then. Hi Snickers!!! Have a great Memorial Day!

Always happy when you post! Thanks for the video! Cool Amplifier!

I love that oak case. I made a CNC mill to make cases like that. I'm working with oak now before I move on to aluminum. My results are great so far. Oak looks beautiful with clear anodized aluminum.

wooooo, new vid from one of my fave diy creators!

Efficiency is more important than Wattage rating, especially when it comes to Subwoofers. Your Demo proves that once again.

Wow cuz this is really helpful work! Congrats and keep it up.

wow 8 years and it works fine! It'll never be a commercial success John :)

Glad to see your bench is as cluttered as mine, it’s a sign of genius

Awsome vid, clearly explained test routine, thanks for sharing. Could not find the link to the test file you mentioned in the video, only the Patreon link. 👍👍👍

Nice amp, you can also try TDA1554- 12vdc to 18vdc- single supply, a stereo- bridged 22w per channel only 5 components so easy to build, it's widely used in audio car stereos before the Mosfet ic-chip came along with 50w

i'm running a dual Tda7294 board from Jim's audio shop, with a uPC1237 for speaker protection and a 150 VA 26-0-26 transformer. works fine so far..

Add to smoothing capacitors can slightly increase the power too

I like that!

Please publish a video on how to select proper heatsink for audio amplifier chips like Tda2030A, 2050, lm1875 etc

I'd love to see the schematic

Holà Una pregunta, se puede conectar unos parlantes y guitarra eléctrica en este tipo de amplificador jvc rx-6010r

Please publish a video on TEA2025 ic

I hope someday you do a transient test/dynamic test,, i have prob with my amp tried to put 3300uf-20mf per rail, that prob is when i try to push to 25+ watts, but 32watts rms is clean

Difference between a passive and an active sub is the length of the speaker wires.

I remember when I learned that there could be power on the heatsink in an atx psu. Fried a cheap meter and tripped a 15 amp breaker.

I wonder if Snickers thought "My human's learned how to purr"

I love this amp... You have the diagram anywhere? I have a test bench and I am a woodworker with a plexiglass bending machine... This is perfect for me.

Volts give you the jolt, mills kills. What's the current on the heatsink?

John, were those subwoofers two 12" in vented enclosure(s)?

What's the maximum safe operating voltage for an unauthentic Tda2050 chip ? I want to make an amp with this chip but can't get an original chip

This is weird, the hardware seems perfectly fine for Windows 10. Ivy Bridge came out during support era for Windows 8.0 or 8.1 and there really isn't much between them and Windows 10 technically. I'm running Windows 10 currently on an Ivy Bridge laptop, same exact generation and similar hardware to your PC, on a Bay Trail Atom tablet, from slightly later in the same era, and on a much older Phenom II x6 monstrosity, though i guess last BIOS firmware update for that came also around that late 2012 era to support newly available processors. Two of these got the 64-bit build of Windows, the tablet got 32-bit due to its RAM shortage. Ivy Bridge is still remarkably fast and highly compatible (all necessary instruction sets present) and i don't see much pressure to upgrade, would be a waste of money. If it's just for Windows 10, it stands to reason that you should be able to accomplish that still. Especially since you might find Windows 10 mildly infuriating (i still do, but i need it for various reasons and am willing to live with the bad for the benefit of the good), and it would be a double disappointment if you found that you had to drop a whole mainboard+CPU+RAM worth of money to get to something that you don't like. You can usually run Windows 10 just fine on most older machines starting with Vista era, 2006 or so, just as long as they have ample RAM - about as much as you needed for Vista if not less, about 1GB for 32-bit version and starting from 4GB for 64-bit. What exactly was happening? If it was failing somehow in early boot stages, perhaps it's an UEFI/GPT thing. on PC and laptop, i decided against GPT, and use the MBR partition table and classic boot instead. Secure boot was too scary for me, because troubleshooting UEFI issues didn't make me comfortable, AT ALL, i simply lack a proper in depth understanding of what's going on there. Sometimes, upgrade troubles are a thing and a clean install of Windows may be advised. Let me know if i can advise somehow.

How is this stereo amp connected to subwoofer and speakers?

At zero volume, your amplifier consumes about 12.4 Watts, that's almost the same as my classic Quad 303 amp that has a max output of around 45 Watts per channel.

You weren't the cause of the Roswell Incident with that base waveform were you?

I have one created myself on perf board without a box.

John,how to boosting output power tda2050 with additional mosfets on output line?

Does the volume go up to 11? SNICKERS ROCKS

Is it a 4 Ampere transformer you used here ?

Do you mean to say that a 2 Ampere transformer can actually deliver only 1 Ampere current maximum ?

Would have been better to have the larger "storage" caps inside the amplifier enclosure, rather than in the PSU. There'll be a lot of sag and droop on the peaks of sinewaves due to the long run of fairly thin cable to the XLR connector. Also I didn't see any shielded cables in the inputs - just twisted - which is a bit dodgy..

nice. but, why the 8 watt is being consumed when the amplifier is off ?

Have you tried Linux?

Has anyone build 5W Class A amplifier around 2xBD131 transistors and 1x BC212L just google for 5W Class A amplifier if you are interested in building it.
