Team,

Just showing-off my works:

1) Poinz's Musical Machine (integrated stereo amp, push-pull design using 5965 drivers and 6V6GT power tubes, 6-8 Watts RMS output/channel),
2) a phono pre-amp/buffer amp combo using a 12AU7 and 12AX7s designed by E.J. Jurich (so that I could play my old vinyls), and
3) the Fostex FE206En Double Bass-Reflex Speakers.

Built everything from scratch. Including the cabinets. They may not look professional (I am a novice). But, they sound great. Hope you like them.

Danny

Congrats on your design, on your next effort,, it might be a good idea to place
the power xfmr in the middle of the two output xfmrs, it looks kinda lonely
so far to the right. this would spread the xfmrs out, and will appear that you
used more of the chassis, nevertheless your system looks quite nice, and,
I am sure you are enjoying those "Oldie goodies"

Steakhead, thanks.

Related to the power xfmr, I followed Poinz's suggestion to keep the PS and related HW/wiring as distant as possible from the signal processing circuitry in order to reduce noise/interference.
This was my first project. And indeed, the amp is very quiet.
