The second picture shows the measured output signal with no speaker load attached while streaming silence. This is interesting as I used a signal generator with my standard HD650 XLR-4 cable and looked at the phase on my Rigol DS1054 oscilocope and pin for pin the input and output are in phase.

As such I would bet this amp does not meet the FCC Part rules section 15B which is a requirement by law and as such most likely is even illegal to distribute in the US.

Probably because the one amp is the basis for many many amplifier types that all look different when under the bonnet it's just the same SS amp. After being lived in Shanghai for a year, my experiences just put me off that anything is made in china, especially Chinese brand.

There is general consensus in the audio world which of the pins are assigned to a signal as used by HIFIMAN for instance. I applied the variable signal 2B to the input of the amplifier and looked where it comes to when the 6n1p and 6p15p lamps were removed.

They could have very easily been honest and up front with this product, and they would have been successful.Where does the signal on the cathode 6n1p and on the cathode and anode 6p15p comes from, if the signal comes on the 6n1p grid only when tubes are removed?
