I put these in the V2 and V3 positions of a VOXAC15C1. They sound good. For the V1 use either a 'V1' rated JJECC83S or a Tung Sol Reissue. Both sound good with the Tung Sol offering a bit more clarity and gain. Both sound good with the Tung Sol offering a bit more clarity and gain.

I have put it in v2,v3,v4 position of my Peavey Ultra Plus following the suggestion of TT. I don't have a lot of experience about tubes but the clean is still sparkly and I don't notify any noise.I've replaced a Sovtek 12ax7 whit this. The crunch and ultra channel aren't noisy also. I'm satisfied and my wallet also! clean is still sparkly and I don't notify any noise.I've replaced a Sovtek 12ax7 whit this. The crunch and ultra channel aren't noisy also.

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. !!
