A lesson that a lot of tube makers have not learned. They seem to have stayed very close to the original bottle specification. Numerous tube swaps were done and the boys would always be able to tell if Polam or Telam were installed.įrom a construction standpoint there is more good news. I had a couple of players testing them and they had no problem in picking these tubes as their favorites. The great mids transition into a smooth clear treble and the bass frequencies are solid with no flabbiness. JJ’s sound flat and one dimensional by comparison. The midrange is very rich in harmonic content. Mesa Boogie, VOX, Dr Z another two thumbs up. Telam and Polam EL84 - Two wild and crazy tubes! I think for single coil guitars they are the best sounding tubes available. I personally like my tubes biased at 60% or 70% of static dissipation and the Sovtek EL84 performed well in this range. Very crunchy yet smooth with great singing sustain.

If you want to really scream try a Pro Junior with full volume. The highs are not harsh, the mids are warm and the bottom end is not lacking. In the Fender Blues Junior the tubes can really put out respectable volume and great tone for all types of music. This is true of any amp that uses an EL84 in a poorly ventilated chassis/cabinet arrangement, so if this is your rig, go for the JJ or Russian EL84M. The heating/cooling cycle inside an AC30 easy-bake oven seems to loosen up the mechanical structures within the tube causing them to become very noisy (mechanically) with time.
Being prone to mechanical noise in a combo amp, the EL84 is not recommended for amps with poor air circulation.
In cathode biased amps like the VOX they get a premium workout and will suffer some effects from heating and cooling. Using a matched set of properly biased tubes will yield a clear smooth sound that is fairly warm and transitions into a smooth breakup with that singing tone that EL84’s are known for. The Sovtek EL84 has been around a long time, and it has shown continuous improvement over the years. You can get good EL84 tone at a reasonable price. It is predictable, reliable and affordable. Sovtek EL84 - The Sovtek EL84 has been a staple for Fender, Boogie, Crate, Peavey and other manufacturers of tube amps using the ’84. If not, try a set of the Gold Lion EL84's. IF you can get Philips, Telefunken, or British Mullard then go for it. If you figure in the extra cost of NOS, these are actually a better value. I would take these over MOST NOS tubes any day of the week. This produces a very nice organic sustain. No gritty, raspy tones, the tubes have just the right amount of compression to track with the overdrive and keep it beautifully controlled while blooming nicely as the note fades out. The plates look to have a different coating than anything else coming out of new sensor in EL84's and this, combined with a heavy gage crimped plate seems to really keep the noise down.Ĭlean tones are chimey and sparkling with single coil pickups and a bit darker with humbuckers. The Gold Lion's just sound great at any volume level. Gold Lion EL84 - All tubes in the EL84 family are tested in a cathode biased amp where they are really pushed and their harmonic content blooms. The $$/tone ratio is excellent with this tube.

To qualify as a Select Series tube, performs a full battery of tests and extra inspection to make sure you never receive a dud. It’s great sounding and well constructed for “professional” use. Many hours of testing in class A single ended amps and demanding push – pull circuits such as the AC30, show it to be the way to go if your amp likes to eat tubes. If you are running older cathode biased amplifiers these tubes are about as good a choice as you can make for this kind of money. To handle those issues the glass has to be just as heavy duty. To get the 7189 designation you build a tube that will handle both higher plate voltages and increased current. These are Russian tubes built for Russia. Don’t confuse these with any other EL84 on the market. These tubes are bold, producing solid fundamental notes and shimmering harmonics. Preferred Series 7189 (premium EL84) - This is the tube you want in just about every amp that calls for a 7189 or EL84.
