Hi,

I have just finished building crack.
I have done the resistance and voltage test.

The sound only comes on right channel. No sound on left channel.
I have reflowed every joint but the problem still persists.

How do I find the source of this issue?

Thanks.

Can you post your voltages on terminals 1-10?

I don't suppose you're using a 1/4" to 1/8" adapter?

Thanks for prompt reply.
Will do the voltage test again

Yes, Im using 3.5mm to 6.35mm adapter.
I dont think there’s issue  with adapter because its working fine when i
plugged it to my solid state amp

I would very, very, very strongly suggest trying a pair of headphones without the adapter.  There are a few varieties of those adapters that don't work all that well.  We used to keep a bin of them on the wall at the old office because we would have to throw them away so frequently.

I found the issue, the foot of 3k 10w resistor was slightly loose and missed during resoldering.
Its all working now.
Thank you!!
