Hello,

Does anyone have APPJ PA0901A / Miniwatt N3 schematics?

I got the one, wired it to my CD player directly.
In this case, I think that the gain of the amplifier is too high.
I don't want to use any pre-amplifier, and I think to reduce the gain by substituting 12AU7 / 12AT7 / 12AY7 for 12AX7.

With the schematics, I could know the possibility of the substitution.

Best Regards,
