# Vacuum Tubes

The first electronic amplification of sound was done with Vacuum Tubes. We have pre-amp, power and rectifier vacuum tubes among other types in New Old Stock from the golden era of American & European manufacturing as well as current production tubes from today.

#### Solid State Replacements

Solid state replacements for vacuum tubes are great for use for hard to find or costly vacuum tubes and for reducing 'sag' in power supply applications.

Vacuum Tube - 6V6, JJ Electronics
This 6V6 has the standard rugged construction we’ve come to expect from JJ which allows it handle much higher plate voltages than the typical 6V6 tube. The JJ 6V6 can even be used in place of a 6L6 in some amplifiers. Overall this tube has a warm and balanced tone with incredible separation and response. These tubes can cover a spectrum of sounds and styles all within the same amplifier.
Starting at $14.95 Vacuum Tube - 6L6GC, JJ Electronics The JJ Electronic 6L6GC is the classic pentode built with the rugged construction that only JJ could deliver. At 30W, this tube delivers plenty of headroom. The highs are clear and responsive with warm mids and tight solid lows. Known for their reliability and articulation, the JJ 6L6GC is a great option guitar amplifiers and Hi-Fi stereo equipment. Starting at$17.50
Vacuum Tube - EL84, JJ Electronics
The JJ Electronic EL84 is a solidly built EL84 / 6BQ5 with excellent tonal qualities. JJ’s rugged construction of this tube offers high reliability without any compromise to the sound. This tube has solid lows with warm bright mids and shimmery highs. When saturated the harmonics are rich and dynamic. The JJ EL84 nails the classic sound of this tube. This tube can replace any EL84 or 6BQ5 tube.
Starting at $10.25 Vacuum Tube - EL34, JJ Electronics Another classic from JJ. This tube features a rugged construction leading to an incredibly reliable EL34 with astonishing tone. Overall the sound is nicely balanced with tight lows, a rich and dynamic mid range and clear highs. The JJ EL34 is a great replacement for guitar amplifiers and stereo amps as well. Starting at$13.95
Vacuum Tube - E34L, JJ Electronics
The JJ Electronic E34L adds more power to a standard EL34 due to its higher grid voltage rating. This increase gives the tube more headroom and a tighter response on the low end. The wide frequency response of this tube offers excellent harmonics that work in a variety of genres ranging from the cleanest cleans to rich and aggressive breakup.
Starting at $13.95 Vacuum Tube - 6550, JJ Electronics The JJ Electronic 6550 is a robust tube built in the rugged fashion that JJ is famous for. At 35 Watts, these tubes have a warm round tone with a thick and defined low end. The JJ 6550 is an excellent choice for bass heads, tube organs, and Hi-Fi amplifiers. Starting at$36.95
Vacuum Tube - 12DW7 / ECC832, JJ Electronics, Dual Triode
In the 12DW7/ECC832, Section 1 of the tube (pins 6, 7, and 8) is the high gain 12AX7/ECC83 spec (gain factor 100) and Section 2 (pins 1, 2, and 3) is the low gain 12AU7/ECC82 spec (gain factor 17).
Starting at $12.95 Vacuum Tube - 6CA7, JJ Electronics A true to form reproduction of a classic tube that will work in most EL34 amps. The 6CA7 is often considered the American cousin to the British EL34. Sonically, this tube is closer to a 6L6 than an EL34 but without the sometimes harsh high end of the 6L6. Starting at$16.45
Solid State Rectifier - Yellow Jackets® YJR, For 5AR4, 5U4, 5Y3
The YJR is a direct plug-in replacement adapter for use in most amplifiers that use 5AR4/GZ34, 5U4, 5Y3 or similar full-wave rectifier tubes. The YJR converts your amp's vacuum tube rectifier to a solid state rectifier, reducing tube sag for a tighter sound and feel. The tube rectifier can easily be swapped back in when sag is desired. This Yellow Jacket® is a solid state device and as such does not come with vacuum tubes.
• Converts most audio amplifiers which use a vacuum tube rectifier 5AR4/GZ34, 5U4 or 5Y3 to a solid state device.
• Safe for all common amplifiers and transformers.

All Yellow Jackets® have a one year warranty against manufacturer defects.
$14.95 Solid State Rectifier - For 5AR4, 5U4, 5Y3 Tubes Solid State Rectifier Direct plug-in replacement for 5AR4, 5U4 and 5Y3 rectifier vacuum tubes in amplifiers with center tapped secondary power transformer. Use when less 'sag' is desired in the power supply; just switch back to the tube rectifier when 'sag' is desired.$9.95
