Vacuum Tube - 7189, Tung-Sol Reissue
Tung-Sol has reissued the rare 7189, a high fidelity audio specific variation on the EL84 tube. In addition to the increased fidelity, the 7189 features a higher maximum plate voltage rating of 400V. These tubes are great for both guitar and HiFi amplifiers and can be used in any EL84 or 6BQ5 position.
Starting at $30.95 Vacuum Tube - EL84S-STR Blackplate, TAD, Premium Selected The Tube Amp Doctor Blackplate series offers the highest tube performance due to the stable heat dissipation of the black anode. This results in an increased tube-life and tones that rival the classic NOS tubes. Starting at$19.95

New-Old-Stock (NOS) tube. Compactron twin-triode pentode.
$8.05 Vacuum Tube - KT66, Tube Amp Doctor, Premium Selected The Tube Amp Doctor KT-66 is an incredible remake of the classic British tube. With its large glass envelope contoured by smooth curves tapering into a rounded brown base, the TAD KT-66 not only looks like the original, it performs like the original. This KT66 offers plenty of headroom for a thick full bodied sound with smooth yet articulate highs. The KT-66 is famously used in vintage British plexi amps and makes a great replacement for that style of amplifier and many others. The TAD KT66 is matched for both plate current and transconductance and passes all of the tests of the TAD Premium Selection process. The TAD KT-66 can be used in any KT-66 position as well as 6L6GC and 5881 amps that can supply the required 1.27A for the heater. Starting at$31.95

The Tube Amp Doctor KT88-STR is build just like the original tube with its thick curved glass envelope and metal base. The similarities don’t stop with its attractive appearance. This KT88 offers a lively and dynamic tone that is ideal in both HiFi audio amplifiers and high wattage guitar / bass amps. The sound of the TAD KT88 is pleasantly warm at all frequencies with detailed mids, articulate and nuanced highs, and harmonically rich and natural lows. The linear response is excellent. The TAD KT88-STR is matched for both plate current and transconductance and passes all of the tests of the TAD Premium Selection process.
Starting at $48.95 Vacuum Tube - 6550A-STR, Tube Amp Doctor, Premium Selected The Tube Amp Doctor 6550A-STR is built and performs to the same standards as the highly sought after GE 6550A. TAD has meticulously designed the plate material to be as strong and pure as possible resulting in an exceptionally stable, consistent, and reliable 6550. The TAD 6550A features a thick straight glass envelope, a metal base, and an authentic triple getter. The frequency response of this tube is remarkably balanced and smooth. Transparent natural lows and thick rich mids with silky highs make this an excellent tube for HiFi equipment as well as classic bass guitar amplifiers. The Tube Amp Doctor 6550A-STR offers outstanding performance in all applications. This tube is matched for both plate current and transconductance. The TAD 6550A-STR also passes all of the tests required in the Premium Selection process. Starting at$49.95
Vacuum Tube - 7581A, Tung-Sol Reissue
Rated for more power than the standard 7581 (35W plate dissipation vs 30W plate dissipation).
Starting at $29.95 Vacuum Tube - 6AG7 / 6AK7, Pentode, Power Metal, power-amplifier pentode primarily designed for use in the output stage of video amplifiers. The tube is capable of operating at high plate current levels and exhibits high transconductance and high power sensitivity.$7.90
Vacuum Tube - 5881, JJ Electronics
The JJ Electronic 5881 is very similar to the 6L6GC but with a plate dissipation of 23W rather than 30W. Another physical difference is the shorter bulb. These tubes have a soft and balanced response that sounds great in both guitar amps and hifi equipment. The JJ 5881 will work in any amp that uses 6L6 tubes.

Vacuum Tube - EL84 / 6BQ5, Tung-Sol Reissue
Due to many requests by fans, the Tung-Sol EL84/6BQ5 has been reissued. The Tung-Sol EL84 / 6BQ5 was a popular OEM tube for American-made EL84 / 6BQ5 guitar amplifiers, such as those built by Gibson and Harmony. Due to its rugged construction and conservative ratings, it is the most reliable current production EL84 type available for use in Vox AC-30 type amplifiers. In addition, its linearity and tone characteristic make it the ideal replacement for EL84 hi-fi amplifiers, such as those built by Fisher, Scott, and Harmon-Kardon. Tube measurements are as follows:
• Height: 2.75” (without pins)*
• Diameter: 0.87”*

*Note: Due to the method of production in regards to the glass, measurements may vary slightly.
