Designed as a medium break-up style, these computer-matched tubes deliver a perfect balance of headroom and smooth overdrive, making them the go-to choice for audiophiles and guitarists seeking legendary tone and durability in classic amps like the McIntosh MC275 and Marshall Major.

## Description

After extensive research and engineering, the famed Genalex Gold Lion KT88 is available once again. Recreated down to the finest detail, features gold-plated grid wire, carbonized screen grids, and a tri-alloy clad plate structure for exceptional performance and sound quality. Soft, medium, and hard style descriptions refer to break up modes of the tube for an overdriven guitar signal. The Genalex KT88 Tubes are soft-rated tubes that break up slow and have the highest amount of headroom, while hard-rated tubes break up easier and have the least headroom, yielding a heavier, harder distortion. Medium-rated tubes fall in between.

## Questions & Answers

**Q: Have these been burned in by you or the manufacturer before shipping?**
A: These tube were purchased because of the really nice prices, they worth the trouble.  I'm not sure the seller burned them in the tubes or any one else for that matter.  Of the 16 I used, I had multiple failures with in the first few weeks.  The failure were all over the place, meaning sometimes just the tube and another times it took a fuse.  Do yourself a favor, find a dealer who burns them in and has a good reputation, it may cost a bit more but it will pay off in the long run.

**Q: Can these tubes work well with MC275 VI?  No bias necessary?**
A: These are great sounding tubes. I have a prima luna amplifier with auto bias, you need to check your owners manual about bias settings for your particular amp.

**Q: Where are these manufactured**
A: New production Genalex Gold Lion tubes are assembled by hand in the Reflektor factory in Saratov, Russia

**Q: Would these tubes go good with a marshall jcm800 head?**
A: They are some of the best KT88's available today. I haven't used them in a guitar amp, but I bet they'd sound killer in a Marshall.
