TPA3116 amplifier on the QA403 audio analyzer

[@billkalina3089]

TDA 7293/4. My faves!!

[@antibrevity]

Thank you! I've wanted to see some of these amps tested like this.

[@bobisyouruncle1]

All your video's are great, John.

[@andymouse]

Same, a good 10 years not a sniffle and this year...a cold !

[@nizzyamps1317]

Thanks for doing these John!

[@TrevorsBench]

Get better soon John

[@billkalina3089]

Ive got a big boxful of stillborn amps John!

[@jj74qformerlyjailbreak3]

I keep all my Still born boards because I know what PP does with the throwaways the Dems sell the Grift as Women's Rights.

[@Bananerocs]

John could you do a video on class d amps output filters and how to improve them?

[@jj74qformerlyjailbreak3]

The ones I bought " TPA3116" had fake chips under the heatsink. They looked like Pam 3w SOP16 package under the hood.

[@AC9BXEric]

If you see a super bargain it's almost certainly counterfeit in some way.

[@nearchd504]

I had that fake tpa 3116 2.1 amp, it was rated for 24 volts but it's sub woofer IC caught fire at 12v , it was powering a 3.8 ohm sub woofer 250watts . It only worked for 15 minutes before it caught fire 🔥

All the hype around the TPA3155 I got one but didn't like the sound and sent it back. Got a refund. Love the TDA7498E though with simular 2.1 power. Love to see a comparison test.☮️🇦🇺

[@doktabob328]

Please test that TA 2024, I’d love to see the results.

[@ats89117]

This amplifier on 4 Ohms has the same frequency response as my ears...

[@ohmbug10]

😂 Same here. Primary metals processing machinery has been rough on the old frequency response.

[@mafhper]

😂

[@diyfullrangehifispeakers]

I do love these chifi amps. Love to see the Lm 386 class A is it? And Tube amp tests. I'll have to look back at you back catalogue for these.☮️🇦🇺

[@aheadtothepast]

John, I enjoy all your videos. Do you recall the name of the video in which you did A DIY schematic for a capacitor leak tester with a high efficiency green LED? I lost a sch ematic notebook. Hope you can recall or maybe you could cover it again in an upcoming video, please? I trust your schematics even though other channels have similar data, I'd rather have your schematic. Thanks so much!!

[@McTroyd]

Kind of a surprising result. I'm using a TPA3116D2 from Parts Express in a stereo config, driving 8 ohm Dayton B652s. If anything, it's a touch bright over 10k. If that PCB wasn't meant as a subwoofer board, as you suggest, they must really have botched the output filter. Or, as others suggested, perhaps this chip was a knock-off?

[@mrb.5610]

Like to see if there's any difference between running one on your regulated power supply and a 'basic' transformer-diode-capacitor one too if you get a chance !

[@gkdresden]

I think higher THD at frequencies of 10 kHz and above are not audible. So it is not very critical to see higher THD at these high frequencies in the measuring curves.

[@jutukka]

I suppose that the TDA 7293 is the power amp chip used in some Boss Katana guitar amps. Many have blown it by shorting the speaker out when changing speaker etc. Could you test how easy it is to get toasted? 😂

[@ConorHanley]

Must've missed the 'new' Quant Asylum Analyzer as that's what I gather is implied by analysing old boards.

[@axxiomm]

Thanks. Please do test on tda7377 tda7850 boards.

[@shyzbyz7996]

tpa3116 is good chip but its difficult to find genuine one

[@Roys_Desk]

Waiting for the JAT 801 to get finished!!! 😌😌😌😌😌😌😌😌

Hello John! I read that connecting opamps in parallel should reduce the THD+noise? I have seen headphone amplifiers that use 2 to 4 NE5532 in parallel for 32ohm headphones per channel. I then thought to myself if 4 ne5532 can drive 32ohms with +-9 volts then 64 ne5532s with +-15 -18 volts should also be able to drive 4-8 ohm loads. Has anyone ever done or seen something like this? 64 x ne5532 should result in an almost perfect amplifier with 15-20 watts. If you use current OPamps instead of the old ne5532, the performance could increase again. But the NE5532 is unbeatable in terms of price and is available all over the world for 0.5-1 dollar a piece. It would be nice to hear what you say about this idea! If possible, it would be cool if you could test whether the THD gets better when you connect opamps in parallel. Am I stupid or does what I came up with make sense?

[@AmritpalSingh-v3u]

Bro test XH-M577 model of tpa3116 Its a good budget amp with volume,bass, treble control

[@nonsuch]

Seems like all it's good for is a tiny subwoofer, if that.

[@Uraim]

I have tested a fake version of this, and got quite similar results: HW-576: 12V: 12.390w till 10% thd 4R load 19.5V: 35.402w till 10% thd 4R load I used a parallel speaker with series resistor with it, so i can hear from the speaker when the sound goes worse. for very low distortion that i wasn't able to notice i got the following results: HW-576: 12V: 3.080w clean power to (under 0.1%thd) 4R load 19.5V: 11.560w clean power to (under 0.1%thd) 4R load So yeah, the chinese copies are way worse, i am at least pretty happy to have good hearing to thd, I am an owner of a Pioneer SA7800 that i love so much due its outputs are so clean.

[@linandy1]

My tda amp looks like yours but they said it was good for 100 watts music out put. 😮 eBay seller.

[@gamiwv]

The implementation of this amplifier is awful.Don't be surprised if under the heat sink you see a 16-pin integrated circuit labeled TPA3116D2. It's probably the CS8673E rebranded (a common scam by some "factories") I was experimenting with 22μΗ and 15μΗ at 8Ohm speaker with 19,7VDC linear power supply (I sorted the reverse voltage protection diode). I didn't like how it sounds (and I switch to an other LINEAR amplifier with NE5532 + TDA7379. Almost perfect sound the later). The TPA3116D2 board is thrown away in one of my drawers.

[@1pcfred]

It's going to take a while to get used to sick John's voice.

[@sarjanapenerbangan]

Di indonesia class d tidak ada penggemarnya.... di indonesia lebih suka class ab. Please check STK4132II dan LM4766 ini favorit chip amplifier di indonesia ... saya akan merekomendasikan video ini di group saya nanti thanks

[@billkalina3089]

Send it to the Asylum...lmao!

[@BefxPL]

You really should measure distortion with limited range of 20Hz-20kHz. Humans can't hear beyond that so the measurements are useless in terms of audio amplifiers. It's not laboratory equipment.
