Looks good
Design and components choice is very good.
VU meter does give it a vintage look.

Does it have internal power supply or external?
Does it have auto power on/off or triggered in/out?

Looking forward to more information and full pictures.

1.HPF should adjustable from 60 ro 120 Hz, the fixed 80hz is too High for same system.
2.The gain control can be bypass or just skip this function.
3.The UV meter has dimmer function.
4. If the UV meters likes Mcintosh style, I will have a pair of it.

Vu 미터는 멋져 보입니다
tpa3255 칩의 최대로 힘을 쓸수있게
내부 전원 부품 용량을 크게 만들어 주세요
vu미터 색깔은 바꿀수 있으면 좋겠네요
그런데 3300uF 이면 모노 파워 앰프로
충분할건가요? 8옴이면 어느정도 파워가
나올까요?
