Sovtek 6L6GC

SKU: N/A Categories: , Tags: ,


These are the original Sovtek 6L6GC tube from before New Sensor bought the name. They are unused old stock made for OEM amp makers so there is no label or logo. They have the flying saucer getter only seen in real Sovtek and Svetlana. They sound awesome and are very sturdy in construction.

Tested on the RoeTest professional computer testing system.

Matched sets are matched by plate current and transconductance using the new Maxi Matcher 2

    I like them, way better than current production Sovtek 5881.
    Can’t beat these for the price.
    I did have a slight issue with one running off on me while setting the bias, the current just kept going up until I no more bias control left. I shut it down before it got too high and started over, it seemed to calm down after that, then I played the amp for a while and re-checked the setting, made a slight adjustment then let it burn in for about 3 hours.
    All in all, I will buy more in the future, if you still have them.

    I put a match set of these in a blues deluxe , 1 1/2 years ago.
    They sound better now than when I installed them, smooth
    And creamy tone ! Lots of head room !

    Popped a pair of these in an Epiphone Custom Blues 30, so warm, decided to switch out the old power tubes on a ’67 Fender Black Face Bassman.

    Popped a pair of these tubes into my 1967 Fender Black Face Bassman amp to give it some new life. WOW! These tubes, at this price are unbeatable. The package was very well protected and shipping took three days from coast to coast. I have a new source for my tube needs. Thank You!

    Had to swap out for Mesa’s due to the base being too large for my amp. But the new tubes are great!!! Great company to do business with. Highly recommend.
