This is a RARE matched quad of Type II Ei KT90 tubes. Type II is the best sounding and most desirable version of this tube, and can be identified by the numberous spot-welds on the plate structure. The tubes in this quad test as-new on my TV-7D/U, and are very closely matched (<5% difference in transconductance).
These are one of the best sounding substitutes for 6550 / KT88 power tubes, and MUCH better across the board than the current production EH KT90. Ei KT90's have not been made since the early 1990's. Please add $15 for insured priority mail shipping in the USA.Get them while you can!
