Not sure why you think the JLE board is higher quality than the 3e. The 3e board performs well and has not had any problems associated with it design. Both of my 3e boards have no background noise and produce amazing sound. The JLE board looks good but this does not reflect quality or good design.

Hi guys,

Give me a few weeks, I will share my opinion about the Jlester module.
As per measurements, it is by far better than the 3E Audio modules.

New version AllInOne amp

 

[Pokerbarlo]

I dont think these boards are really pushing 150watts into 8 ohms i got it connected to a switching power supply rated at 48v 12.5amps pushing 4 bass shakers in parrallel and the bass shakers are rated at 50watts 4ohm. 2 to each channel tried series as well. Very weak amp.

.... Very weak amp.

What amp are you talking about?

I need to fine-tune the sound signature of my module, still waiting for the input capacitors. Might take another week. Thanks!

New version AllInOne amp

Nice, L6599AD for LLC SMPS. Any other purpose of bleeder resistors for PVDD?

New version AllInOne amp

Is this a 2 channel power amp with integrated power supply?
If so, from where would I purchase these drMordor?

From drMordor personally.
Akita "AllInOne" Amp based on TPA325x PFFB+ and LLC PSU in one board.

There is a new (to me) 6-channel variant of the amplifier boards with TPA3255 popping up on Ebay:
TPA3255 Amplifier Board DC24-48V 400mA Electronic DIY PCB w/ 3 Fan Design | eBay

It uses three fans, each for 2 channels of the amp.

Has anyone tried these, or the 2 channel or 4 channel variants?

 

[drMordor]

This is hoverboard)))) (C)

Hi Everyone,
From where I can buy 3E Audio TPA3255 stereo amplifier board? It is out of stock on Aliexpress and their website point to Aliexpress marketplace only. Any other place, where I can buy the same?

Thanks,
Simar

I got a 3255 board from amazon for $50. I am eager to try it out.
the specs look impressive at 35 - 40 v supply.

Hi amigos,

Seems that a New TPA3255 with integrated PSU is now available :

TPA3255 2.0 numerique classe D Bluetooth 5.0 aptx amplificateur de puissance avec alimentation a decoupage | AliExpress

For me those Chinese design are becoming worth and worth....

Why don't they just sell a power amp with balanced inputs, without op-amps, volume control or tone control for 100?

What about this one?

OK, ok, hoverboard jokes aside... can someone comment in a serious way on this amp board? 6 channels in a compact package for $100 has me dreaming of its active speaker possibilities.
