Its power can do 200 W 8 R (+ 65 V). So I call it the L 20 D.

This version after four times improved. Scrap a lot of PCB to attain my design requirements.

In the test of the wave and test performance he almost and IRAUDAMP7 is same.

And before the same circuit design out, but often appear waveform distortion phenomenon.

I'm glad someone can like this design. It is very small, very beautiful. And a good voice, power is big enough.
Hi ljm_ljm.
I'm from Brazil.
I recently purchased via Ebay 02 amp boards L15D and L20D.
I would like to congratulate you for the quality of the plates and the ease of assembling them.
I also wish you send me the schematic of the plates L15D and L20D.
Thank you for your cooperation.

I've got about 6 Elna Carafine 22uF caps laying around that I can swap out with the stock caps... Any idea where they'd best be utilized? (L25D boards)

Capacitors. Input capacitance. Free and there is not much restriction.

Some friends also possible to directly short-circuited. Although I did not do so.
