Genuine British made Genalex KT-88. Closely matched on my TV-7 ( 60 on my TV-7)One pair came as matched by IEC , in rather tattered original boxes, once taped together as a pair. The other has oval blue G.E.C. label, also measuring 60 on my TV-7. On all getters are pristine and full sized, indicating no wear, although the second pair are in white boxes. Original GEC tubes had the reputation of being very detailed with a sweet top end. If properly biased, they can last many many years. Prices are for each tube
