Sorry,i am wrong.

V+=+15V,V-=-15V,in the schematics Mic1 and Mic2

Interesting idea, but I think it would only catch on in Asia (primarily Japan).

Thank you.
I am Vietnemese,Karaoke is very popular in Asian countries.

Japan is the starting place but I think it is most common in Vietnam, Korea ...

This is a combination of tube and solid(Hybrid), I see the need to put solid circuit to easily coordinate impedance

Thank you.

Tube makes vocals became smoother, warm ...

I think so.😀

I only used opam for the purpose of reducing impedance
