JJ EL84 / 6BQ5 Power Vacuum Tube


The JJ EL84 is a great replacement for any EL84 / 6BQ5 tube. It offers reliability, great sound, and has a low price. We were surprised by the quality from this tube. It is as good as some of the early NOS varieties like Mullard and Amperex. These work perfectly in Scott and Fisher amps as well as any EL84 guitar amp.

Price is for a single tube.

    Been using JJ EL84's going back many years. My amp is a Crate V1512. These tubes sound rather bright to my ears, with bass response a little lean. I tend to use the tone controls on the Crate to boost bass response and cut mids with tubes like the JJs. One shortcoming of this last pair I ordered--one of the tubes has a hot spot on the filament which flares up briefly upon every power-up. This is a manufacturing defect which may end up shortening the lifespan of this particular tube. Also, I think I'm hearing some microphonics from time to time. Overall though, I think JJ EL84's are a good value.

    My amp beats up power tunes and these are a nice price and what Matchless ships with. Will have to wait and see on longevity, but sound punchy.

    I always use JJs' in my Peavey Classic series amps. They just work.

    Outstanding tone. Put a pair of these (24hr. burn and matching option) in my Crate Vintage Club 20W. Sounds fantastic and clean burning.

    Bought two of these for my Crate VC20 amp (along with 3 JJ 12AX7s). After replacing all 5 tubes, the amp sounds great--as good as it ever has in my opinion. I bought them because they had good reviews and were reasonably priced. I'm happy with the purchase.

    I think JJ preamp tubes are overrated but I do like the power tubes. That said I did have a pretty new EL84 fail but who knows what caused it. I chose a matched duet for my blues junior based on there reputation for being tuff and I think the JJ's are a good match for that amp.

    I ordered a second set on sale for my 2 Dyna MkIV mono amps. Very pleased with the sound. Tube Depot is first rate in my book.

    JJ's are a solid choice for reliable tubes. I don't think they are the best sounding but a good all around tube when considering price vs quality. They also tend to perform better than more expensive tubes in amps that run higher plate voltage.

    Used these as a replacement for the original Miniwatt tubes in a Kriesler 11-95 radiogram from the 70's. Excellent bang for your buck. Would recommend these. Do what they are meant to without any fuss.

    A must for just about every amp I've ever owned. Great price and great sound. Sometimes I don't even try out the stock tubes before putting these in, I always end up going to the JJ's anyway.

    The JJ EL84 is a valve I keep coming back to whenever I build a new amp. It has a solid, full range that never sounds dull or muddy. I especially love it for single ended guitar amps.

    These are rugged tubes, even though they are cheap in price.
    Tubedepot put the bias # on the box, and I hadn't asked, nice.
