Is this amp self biasing? Can it use upgraded tubes like 6550's?

If you are hoping to roll tubes, you will want to look elsewhere. But having said that, this is a nice little amp when paired with fairly efficient speakers.

does this amp have Bluetooth ?

The point of s tube amp it to preserve a high quality (hopefully analog) source. Connecting a Bluetooth source is pointless. This company gets it.

Would this amplifier support 350Bs with their slightly higher heater current requirements?

The amp will automatically adjust the bias so no need to do anything

Do you need to Bias this amp or is it self biasing?

The amp is self-biasing therefore there are no bias adjustment pots on this amplifier.
