Hi guys.

This is a TA2020 amp with 2 extra 3300uf caps and jantzen input caps that i made recently. It is in a glass jar with a enamel spray painted metal cover. I am very with the result. What do you guys think?

nice idea

, but looks like it will have thermal problems..

i thought about that too. so far it stays very cool though. i don't think the ta2020 gets really hot.

My Class-D subwoofer amplifier housed in a small case.

Using +-65VDC rails with 500VA transformer. I conducted sine wave power measurement and the results were 306W into 4 ohms, and 490W at 2 ohms resistive load (clean sine wave before clipping).

Power supply rails sagged from its original +-65DC to only +-51VDC when drawing 490W.

Hello, I'm new here.
It’s great to see everyone’s photos of their DIY projects.

Here are a couple of my class D projects.

Testing a Lapai 2020 to see how it sounds before bypassing the tone circuitry and upgrading the inductors.

A YuanJing TA2020 board installed in a shadow box from Aaron Brothers.
I often use this box to test components and various amp and preamp modules, both tube and solid state.
Here I have it set up to be switchable so that it can be used as an integrated amp or as a purely passive preamp. It houses a 25K TKD stepped attenuator and Cardas & WBT input/output hardware.
