What are the mating connectors for Molec 538-22-27-2021 and 538-22-27-2031?
The mating connectors are not listed on BOM.

See if those work.

The audio input is standard 2 pin Molex KK.
You could use another brand here like JST or even plain 0.100in pitch header pins and DuPont connectors used in Arduino breadboards. Or solder flying leads.
These are the mating parts and crimps to your question Namghiwook:

@Vunce Thank you so much. These are exactly what I want.
Anyway, I have some progress for this amp.
I've ordered a transformer 400VA dual 37-0

Thank you!
W101, W111, and W121 are 0.0ohm.
Sort of jumper wiring. right?
And I need to order this part additionally.
V121 MPSA92

Just a heads up…
I used a single strand of Cat5 copper wire for those jumper positions. The hole are very small, no bigger than 22ga will fit.

Thanks Vunce. I was thinking of the earlier version of this board when I had to jumper the power rails together. This is just a small signal jumper so 22ga wire is perfect.
Some progress.
I've connected all of them.
It made sound indeed.
I listened several songs about 30 minutes but the heatsink was not hot or warm .. actually it was cold.
Also I checked the bias through the TEST POINTs (x1031 - x1032 and x1033 - x1034) but the DMM read 0.00mA
And I turned off the power then the playing music is going on about 30 secs
I've connected all of them.
- Soft as Feather Pillow Starter
- 400VA 37-0 dual secondary toroidal transformer.
- All Cee's PSU
- FH9HVX
- right input channel
- right speaker

Congrats namghiwook! It sounds like you have a functioning FH9HVX! I'm a newcomer to this hobby so take what I say with a grain of salt. However, when I was measuring bias I thought I had my DMM set to measure DC mV. Maybe someone with more experience could weigh in.
Otherwise, there is is great deal of helpful info on measuring and setting bias earlier in this thread good luck!
