 I just put 12BH7 in bhc+sb, but the sound is only on the left side. Is this any changes on circuit to run both 12bh7 & e80cc? This changes can be rolling all tube(12au7/12bh7/e80cc) after that?

Regards,
Colin

Even without the circuit changes the right side should be playing normally when using a e80cc/12bh7 in crack+sb.
So i guess it's time to go back to the voltage measurements.

After i moving(put over/slightly hanging) the bh7, the sound just normal back. Is this a problem with my tube socket?

You likely have a loose connection in your amplifier.
