Headroom Notes

The lowest row of Douk's supply table is recorded here, because on this model both adapters are marked optional in the packing list - the amplifier can arrive with no supply at all, and with no supply there is no power figure. Two JAN5725 tubes run at 100 V in the input stage; the output is the same TPA3255 as the rest of the family.

What the datasheet actually says

Quoted verbatim from the manufacturer’s own page, with the date we checked it. We state what is printed, not what anyone intended by it.

Measurement conditions
«Packing List: 1×T6PRO Amplifier, 2×JAN5725 Tube, 1×DC 32V Power Adapter (Optional), 1×DC 48V Power Adapte(Optional) — Max output power: 300Wx2 (@4Ω)»

Every power figure this amplifier has is conditional on a supply that the packing list marks as optional. The manufacturer's own table gives 78, 120 or 250 W per channel into 4 ohms depending on which adapter is fitted, and the product name quotes 300 W, a value that appears in no row of that table.
