With active PFC?

My CxD500 subwoofer amp is now complete. Building it was a smooth sailing with only a few small hiccups 🙂

Hi
Can you provide more information or a link to the SMP that you use to this amp?

Why did you mount the 500A modules upside down?

since this is all passive cooling, its the only way to get the heatsink to touch and dissipate to the enclosure without making custom angle brackets

Invisible amplifier

Small project for my home office. A TDA7492 PCB from Ebay and an old electronic Enclosure. I printed a holder for the PCB, Rectifier and Capacitors. A small circuit for the VU Meter with an OP Amp i also fit in the Enclosure. I Use also the Knobs from the original - so ON/OFF, Volume work with the same design before.

Invisible between the other measuring devices
