After the original Sylvania 6L6GC tubes in my Peavey VTM60 head - from 1987 - needed to be changed, some 12 years ago, or so, I've tried different brands of tubes, but the most reliable and greatest sounding tubes for my amp have turned out to be the EH 6L6GC and the Sovtek 6L6WXT+.
The Sovtek and the EH tube is in fact excactly the same tube. The EH is only a rebranded Sovtek 6L6WXT+.made at the same factory. in Saratov, Russia for the New Sensor Corporation. They sound exactly the same.
The old Sovtek 6LGC was a completely different tube, and the 20% increased power some refer to is compared to the Sovtek 5881 or the old Russian 6P3S and likes.
These tubes are often sold and mis labeled as 6l6GC tubes, which they are not...
There's a lot of misinformation about Russian tubes it seems?
I play mostly Classic Rock and Heavy Rock, and for my style of playing these tubes are just perfect. At loud volume they compress and distort early with a warm sound, but yet they still remain detailed, and I like that very much. They are also quiet, with no hiss and microphonics at all, and they take a lot of beating. In fact I've never had a failure with any of these tubes. Passed the road test.
I also like that they are not so expensive. Thanks to Tubedepot for great prices, great service and great tubes.
