Price is for 3 tubes. Ultron 12AX7 ECC83, seamed top like an Amperex, same philips plates, halo getter, it looks like a Bugle Boy. These are what some call 'Indian Mullards', a philips tube made in India back in the day. Nice 12AX7's! They appear to have not been used and measure within NOS specs. Amplitrex tested, these tubes meet or exceeds this criteria for a NOS tube: audiotubes.com/nosnote.htm. The gold sharpie near the base is a code I add to each tube for tracking measurements, and is easily removed if desired.
