Russian EL84 / 6BQ5 power tube with 9 pin base



Unused, old stock EL84 / 6BQ5 Power Pentode. The Russian EL84 is extremely reliable and good sounding. This EL84 model has been used in the production of new amplifiers by such manufacturers as Mesa Boogie, Fender, Crate and Peavey. This EL84 is of an exceptionally sturdy construction and when driven can produce a pleasing¬†warm, smooth distortion. Excellent replacements in vintage VOX AC-30’s.

Tested on the RoeTest professional computer testing system.

Matched sets are matched by plate current and transconductance using the new Maxi Matcher 2. They are not matched by date code. Date codes shown in photos are not necessarily the date codes that will ship.

    Beautiful NOS double matched tubes at the best price by far.
    These are highly rated and Nesstone service and products are top notch.

    This company did me right, a nice match on a quad of 2012 Sovtek EL84s. In my AC30TB they sound great, guieter at idle than my old quad of 6P14P Saratovs. The price here is unbeatable anywhere, a great deal! Thank you!

    Best Price; fast shipping. These were same brand as originals on my Peavy Delta Blues, but these sound brighter. I’m very happy with them.

    Very pleased with my order, just wish there was more selection and description. Will always be my goto however!!!!

    Plugged these matched tubes into my Carvin X60A 60 watt amp. Fired it up and was pleased to hear that crunchy sound of overdriven sound. Very happy with the service and great products at a reasonable price. Have already placed another order for some Preamp tubes this time. Thank you for getting my amp up and working.

    My reviews got mixed up although I am still very satisfied with my matched EL84 tunes for my Peavey Bravo amplifier. Looking forward to the next order when I can swap out the preamp tubes to check them out in my Bravo combo amplifier. Thank you kindly.

    Thanks Craig for packing the tube’s well and delivered quickly.
    It took around 10hours to break in.
    I am using Sovtek EL84s on my Leben integrated amplifier for the output/power tube’s. It’s really fantastic, the sound stage is bigger & also to mention the distortion is not noticed.

    Really enjoying

    Sound great in my Vox AC15C1. It really help tame the highs in that amp.

    Unfortunately My Amp has other issues besides tubes. So I did not get a chance to put them to the full power test. Pretty evenly matched only one slightly different.

    Great sounding set of tubes. They deliver that el84 tone perfectly.
