Tejas Tubes was founded by a musician for musicians and audiophiles. We provide excellent testing, screening, matching, and grading of top quaility NOS vacuum tubes. If you are looking for the best in vacuum tubes and service, you have come to the right place.
All tubes are completely tested for gas, shorts, leakage, and transconductance on our unforgiving, COMPUTERIZED and calibrated Hickok 118B cardmatic tester and our Amplitrex AT-1000. Balanced triode tubes are available in limited quantities as most lots will contain only 10% where both triodes are balanced. Balanced tubes for phase inverters and other applications are an extra $10.00 per tube. Power output tubes are also tested and matched on our Amplitrex AT-1000 as well as our Maxi-Matcher to provide tightly matched pairs within 1-3 milliamps of current draw. Pre-amp tubes are screened for noise and microphonics on our Vacuum Tube Valley Tube Characterizer. All pre-amp tubes are noise tested in an actual circuit at our facility for microphonics and noise and in our VTV Tube characterizer, and then dual section tubes are further graded for the closest section matching possible. We also use an independent laboratory for critical noise screening for Super Low Noise tubes for phono sections, microphones, and other critical applications. Please call us or email and let us know the grade you are looking for!
