Two 12AU7 tubes. The manufacturers are HAMTRON and Toshiba. The HAMTRON tube comes with its original box, but the Toshiba tube does not. The model number on the Toshiba tube is faintly readable, but the manufacturer's name is only barely legible, with just the "shib" part visible. I do not have any equipment to test these vacuum tubes at the time of listing, so I have not been able to confirm their functionality in a device. However, I have confirmed heater continuity. I will ship via the "Nekopos" delivery service.
