Description

2 tubes, matched as pair

The 6CA7 is a powerful power tube developed in the 1950s by General Electric (USA). It is electrically largely compatible with the European EL34, but more robust in construction and differs in sound behavior. Both tubes are electrically interchangeable. The 6CA7 offers an alternative sound color and more robust operation at high power due to its Beam Tetrode design. Those who prefer more headroom, warmth, and depth in sound often choose the 6CA7.

Technical Comparison: EL34 vs. 6CA7

Feature	EL34	JJ 6CA7
Tube type	Pentode	Beam-Power-Tetrode (beam power)
Socket	Octal (8-pin)	Octal (8-pin, identical to EL34)
Heater voltage (Uf)	6.3 V	6.3 V
Heater current (If)	approx. 1.5 A	approx. 1.5 A
Max. anode voltage (Ua)	800 V	800 V
Max. anode power dissipation (Pa)	25 W	25 W (partly more robust)
Screen grid voltage (Ug2 max.)	450 V	500 V
Amplification factor (µ)	approx. 11	similar, slightly higher
Construction	Slim glass envelope	Larger, wider envelope
Pin configuration	identical	identical
Sound character	„British“ – centered, assertive	„American“ – warm, powerful, round

Kit Seriel FX-Loop LND150

Active, serial FX-Loop for a subsequent installation in an existing tube amplifier
The FX-Loop works with two LND150 in the send and in the return stage. The send and return level can be adjusted to their optimal value with two potentiometers. The Loop works with the present high voltage of the amplifier.
It has two inputs for low and high signal levels.

Input Levels:
InA: 30 - 60 Vpp, max. 65 Vpp
InB: 10 - 15 Vpp, max. 18 Vpp

The FX-Loop utilize POTENTIALLY FATAL HIGH VOLTAGES.
Seek help from a competent technician if you are in any way unfamiliar with high voltage circuits.
Use at your own risk.

Custom Shop Faceplate Standard - 600 mm

Custom Shop Faceplate, Transply, laser engraved

Max. Width: 600 mm
Material:
- 1,5 mm Transply all Colors starting with #C
- 0,8 mm Transply all Colors starting with #D
Working area: see option list
Colors: see option list
Engraving: Yes
Cutting: Yes
Resolution: max. 500 dpi
Machining: Laser

Important:

We will not produce faceplate which contain copyright-protected elements like logos or names !
Minimum size of an plate: 5 x 5 cm
Smaller objects should be connected to larger objects otherwise they can get lost. Example: connect the i-dot with the rest of the lettering for a cut-out lettering.
Minimum distance between two blades: 3 mm
Bitmaps and Inkscape: If possible DO NOT use bitmaps, because this causes many problems: the PDF file could be corrupt or the quality of the finished product is bad etc.. Bitmaps should always be converted to vector graphics before they are used in the layout. There are numerous online converters which convert bitmaps (PNG, JPG etc.) to SVG. Use them, convert the Bitmap and avoid problems.

How does it work ?

First of all you should read the documents and infos on the TT LaserShop Pages !

a) Select the required size, material and color combination

Hint: Several objects can be placed on a work surface, so cost-efficient material processing is possible. Example: two plates with a size of 55 x 490 mm (front and back plate) can be placed on a work space H2 with the overall size of 150 x 600 mm and can be ordered together. The configurations and optimizations have to be present in the submitted data.

b) Submit the order through the online shop.

c) Prepare the data according to our specifications. You can UPLOAD the finished data below on the page or sent it to us after completion of the order by e-mail (info at tube-town.de).

d) That's it. The rest is our job.

Note on the Parameter "Plates per Sheet"
The number of plates or logos per sheet. The more plates are on one sheet the longer the runtime is. We can make a maximum of 40 plates per sheet.

Note on "Logo-Option"
If your data contains large areas which need to be engraved (mostly seen on logos or plates for stomp-boxes) then you should check this option then we will engrave the plates twice to make sure that the quality is a as good as possible.
In principle, however, it should be avoided to use large, monochrome areas because one will always see small lines from the laser engraver.

!! IMPORTANT: WHEN CREATING THE PDF FILE, MAKE SURE TO CONVERT THE FONTS TO CURVES. !!

JJ ECC803 / 12AX7

Sonically similar to the "normal" JJ 12AX7, but the overall sound is "fuller" and "stronger" with a more powerful bass. Visually, compared to the normal JJ 12AX7, the long anode plates stand out, as well as a slightly higher current. Suits well in guitar and bass amps, but also in audio and high-end areas.

Note: Tubes equipped with long plates are commonly associated with a "warmer" or "richer" sound, whereas those with shorter plates tend to deliver a "tighter sound". However, tubes featuring long plates exhibit increased sensitivity to vibrations and mechanical disturbances, rendering them less ideal for critical applications.
