500W@4Ohm AMP module.

Nice amp modules 👍😛 Any more interesting info about these?

Thanks!
Self-oscillating amplifier based on UcD technology with combined feedback and ultra-deep loop gain. feedback in the audio band after the output filter.
An IRS20957 with an additional discrete transistor stage is used as the output HB driver. Modulator on TL3116+ OPA1602. The modulator uses a 2nd order pre-filter, and a 3rd order "integrator".
For the convenience of use the board is equipped with two-level power regulators for the operational amplifiers and a step-down converter for the driver IRS20957, so no additional power supply is needed. The instrumental preamplifier on the OPA1602 with universal DIF/SE input is also on the board.

Hello,
I would like to show you my newborn class D amp:

 

[Cardone]

Thank you for sharing. 👍

Please note that the size of the case is 25 by 18 cm. The maximum power is 600 watts. 300 watts per channel 4 ohms. Try to reduce the size of the case without resorting to a separate placement of the power supply

Nice build from DIYer.

I re-housed my Orchard Audio Starkrimson Ultra amplifier into a pair of monoblocks. I upgraded to Micro Audio power supplies and custom built enclosures with the help of some Galaxy side panels. I mounted the PCBs to pieces of aluminum and mounted those to the galaxy plates via the hardware channels. I did the same with the foot plates. I incorporated plexi to ensure maximum transparency (lol).

Great job.

Class D amp back in the main system. Giving its Class A brothers a break in the hot summer. This is a pair of @abraxalito’s transformer input TDA8932 MonoAmps in an old chassis. They sound beautiful.

Big heatsink with a hint of audiophile grade vintage MDF..... and an ICEpower 2000AS2.... quite cool.

 

[63781]

Even with this very large heatsink, the temperature exceeds 30 C with an ambient temperature around 22 C. The output coils also get very hot....

 

[zerokelvin99]

Heatsinks don’t work if they’re cold, especially if they rely on convection

 

[63781]

Sure, but the more effective it is, the lower will it's surface temperature be.

 

[63781]

That ICEpower 2000 AS2 module use 38W in idle, which is quite a lot.
