The latest version of our TAD KT88-STR is built in the style of the early British MOV KT88. It has the same big and heavy glass envelope and beautiful polished metal base. Wonderful tone and great appearance make this tube the most attractive choice for high-end audio applications and powerful bass guitar amps. It delivers a three-dimensional tone, which is very pleasing, warm and detailed with subtle highs. Very musical, this tube offers finest details in the mid-range and the top end. Linear, harmonious overall response with a very natural sound make the TAD KT88-STR our favourite in the KT88 and 6550A classes.
