|Before your next show with your band, make sure to check all of your audio equipment, including your trusty old amp. Many musicians prefer the punchy tone of an antique amp during their live show; if a vintage amp requires repairs, a modern amplifier just doesn’t produce the same rich tone. If your amplifier doesn’t work, the problem may be with the tube and tube socket. The tube and tube socket is a type of electrical socket that works to power audio devices, such as bass amps, preamps, radios, and TV sets. It works in conjunction with a vacuum tube to produce the electrical current that powers your equipment. A vacuum tube is an evacuated container that permits the flow of electrons to provide power to the device. This electrical current flows between the electrodes of your device’s tube and tube socket. Pins connect at the plate of the tube to create a circuit. Since your tube and tube socket conduct electricity, it is important to use tubes original to the unit, such as this Genalex Gold Lion KT77 vintage tube and tube socket. The KT77 tube is an affordable, vintage tube that provides a high level of performance. When you are searching for tubes, stick with tubes original to your device during your search. Though other tubes may fit that old bass amp or TV, they do not provide the same performance as tubes that are authentic to the unit, like the Genalex Gold Lion KT77 model. Even if other tubes power the device, they do not last as long as genuine replacement tubes. One drawback to using tube electronics is that the tubes fail fairly frequently, leaving your amp without power. Be prepared for the next failure by keeping extra KT77 tubes in your repair kit. As you search for fresh tubes, you encounter numerous options for quantity, such as single tubes and pairs of matched tubes. If possible, opt for the matched KT77 tubes so that you start building your supply of extra tubes. Some vintage tubes are becoming too difficult to find; buy them while you can, so you are prepared when they go out of stock. Since KT77 tubes are a valuable resource for musicians and electronic hobbyists, it is advisable to make sure the tube is dead before you replace it. Add a tube and tube socket tester to your tool kit. A tube tester quickly lets you know if your tube has any life left in it. Using a tube tester is simple; just plug the tube into the tester to check on its condition. Once you know it is dead, the procedure to replace it is easy with a bit of practice. You’ll be back to enjoying your audio amps with a distinct nostalgic tone in no time.|

Genalex G.L. KT77s = a Huge Soundstage
I am lucky to have amp that is very forgiving and allows me to explore a variety of Tube Types. The only tube that I must use is an EF86 Preamp. The chassis is stamped EF86, ECC83, and EL34, although the builder has told me that I can swap out the inverters (2 - ECC83s) and the drivers (4 - EL84s). I should note here that the amp is a derivative of the famous Knight KB85, with circuit modifications invented by Mullard. Anyway, siffice itvsay that it will run an EL34 with the same spirit the it will drive a KT88. In this case, I had been running EH EL34s.. and Russian 6N/S3Cs. Both are very nice tubes with excellent range... but when Genalex Gold Lion KT77s arrived and I put them in... once I finally put some music on, the soundstage grew exponentially. My test recordings were Chic Corea Akoustic Band, Digital Master; Norah Jones, Come Away With Me; The Dave Brubeck Quartet, jazz impressions of japan. I chose these three because the recordings are high quality and do not require any bass boost, trebel adjustment, etc. I can run them with all tone controls defeated, which is my Gold Standard. What did the Genalex bring to the table? The tonal quality is, to my ear... equal with any tube I have used. Drums pop. Keyboards dance and the sustain is real when apllied by the keyboardist. But the single hardest thing to duplicate is soundstage, and here, the Genalex excels! On track one of Akoustic Band, Bessie's Blues, Chic Korea and Drummer Dave Weckl play extraordinary solos that serve as counterpoints, and set the stage forvthe rest of the slbum. The Genalex Gold Lion KT77s, really bring out the placement of the drums vs the keyboards, and even the tom toms, in relation to each other and the bass drum. John Pattitucci's acoustic bass solo is front and center during this wonderful song that is among the best jazz instrumentals I have heard. Dave Brubeck needs no introduction and his Jazz Impressions series are among the great jazz classics. Playing the CD version back to back.with the LP, I did notice that the LP offered slightly more clarity... especially in the bass. But regardless, the Genalex tubes handles the biggest bass passages, along with the softest piano, withbequal aplomb. Another thing I noticed was that drum tuning had nore clarity with the Genalex. Because I purchased these tubes with 200 hours already on them, I was not able to observe the burn in period. However the end result is a beautiful, sonic experience. On Toki's Theme, the third track on Jazz impressions, the woodwind - an Alto Sax played by Paul Desmond takes on an almost Clarinet like quality... something which was more clear to me using the Genalex KT77s. Overall, the tubes provide a clean, crisp presentation. Musical instruments are clear and the harmonics associated with them are evident. Vocals are realistic... and most important, they sound "real". I feel b as if I am in the recording studio.. not half a century and a thousand miles away. I plan to continue using the Genalex and want to try replacing my vintage RCA ECC83s with Gold Lions as well.
