KT88 power tube reissue of Genalex Gold Lion. Made in Russia.

In 1957 Marconi-Osram Valve Co. (Genalex) introduced the "King of Power Tubes", the legendary Gold Lion KT88. This tube became the heart and soul of such classics as the Dynaco Mark III, McIntosh MC275, and Marshall Major. Unfortunately, Genalex ceased tube production in the early 1980s and the Genalex Gold Lion KT88 has become very expensive and hard to find.

After extensive research and engineering, New Sensor Corp. has reissued the famed Genalex Gold Lion KT88. This tube has been recreated down to the finest detail with gold plated grid wire, carbonized screen grids, and a tri-alloy clad plate structure for exceptional performance and sound quality.

Bought (8) eight KT88 in matched sets of four. One appears to have been defective as it arced at the base (I saw it), and it blew my B+ fuse. My amplifier is now in the shop to see if any other damage was done. If this is indeed one bad out of eight, it is not a good track record. Will update further if is allowed when I get it back from the repair shop.

I absolutely love these tubes in my vintage Marshalls. They are very musical and rich sounding. With head room for days. KT-88 Genalex Gold Lion tubes are far better than any other brand 6550 or KT-88 that I have tried and very much worth the extra cost. I plan to use them in all my vintage Marshalls from now on. Thank you Amplified parts for suppling me with greats parts. :)
