Description

New Gain Tested Tung-Sol 12AX7 / ECC83 Vacuum Tube

The Tung-Sol 12AX7 is one of the very best new production 12AX7 models offered. These tubes are high gain, low microphonics and are VERY warm and detailed. You'll get true 3D sound with these. The filaments are almost completely encased within the plates so they don't light up much, but they are fantastically quiet. The tone is comparable to the best vintage 12AX7s like Mullard or Telefunken.

Will work in place of: 12AX7, ECC83, 12AX7A, 7025, 12AX7WA, 12AX7WC, 12AX7WB, ECC803S, CV4004, CV492

Testing and/or Matching

At VIVA TUBES, all of our customers get the same high standard of testing and matching. Some sellers charge more for premium matches but we believe all of our customers should get the same level of quality and service. 

Tubes are tested and/or matched at full operating voltage with regulated power supply on a Maxi Matcher tester for general mutual transconductance (Gm). In addition, power tubes are tested/matched by plate current (Ip) and preamp tubes are tested/matched by gain. Rectifier tubes will be tested for emissions on a calibrated military grade tube tester. 

Our goal is to match within 5% with an upper limit of 15% (15% is the industry limit to consider a set).

Hand written test data included.

Note that we do offer a few models which are tested & matched at the factory. They will be matched by the same parameters (Ip & Gm) but to the manufacturer's standards. Factory testing will be indicated in the item title and description. 

Guarantee

We offer a minimum 90 day guarantee covering functional defects - including noise unless otherwise stated. The guarantee period begins the day you receive your order.

    Game Changer

    Posted by Gator on 19th Oct 2023

    I replaced the jjecc83 in my Peavey Classic 30 V1 and also the el84 quad with Mullards. I use a sovtek 7025 in the PI with a Celestion Vintage 30. I’ve tried all the highest suggested tubes in the V1 position and this by far is the most hifi, quiet and articulate tube of them all. I was having a problem with the useable treble, as no matter how I tweaked it, the amp sounded either shrill or muddy, none of that delightful in between too just punch through the HEAVY midrange of this amp. Well this tube instantly fixed that problem, scrubbing that wooliness off the top end and bringing out this really crisp sounding treble that actually had a nice useable sweep on the knob. I strictly play through the clean channel of this amp with an assortment of boost/drive pedals and modulation. No idea how this would work out on another amp, but for you Peavey Classic 30 cats out there. This is the one!!!!!
