weird valves

[stubblepoo]

on my new chinese valve amp there are 4 sets of tubes. 3 of them i am familiar with (el34,kt66,12au7 etc...) but one set i am not. the valves it came with have a photoelectric(?) strip on the front which acts as a visual equaliser. just wondering what its called and where i could find new ones if these ones break. cheers
