Jürgen from NixieKits.eu is working on a new design for a line level preamplifier. This new device will have the same footprint as his headphone amp and he has been kind enough to share the schematics so far. The cool part of this design is that will support a range of tube with both 6v and 12v filaments. For example the ECC81 / 82 / 83 (12Ax7) have a 12V filament. All "newer" tubes, e.g. ECC88 / E802CC... and all Russian types (6N1P...) have a 6V filament.

If you've ever wanted to play with magic eye tubes, this is your chance. Jürgen Grau designed a versatile little gadget that allows you use several different types of indicators. The secret is that he has a circular PCB that actually can be rotated to accomodate different types of tubes. The base PCB has three different sockets to provide a universal connection when used in conjunction with the top PCB. That is clever. Best of all - they should be for sale soon!
Jürgen sent me this photo of a new work-in-progress device. What do you think it is? (Leave a note in the comments or on Facebook)
I just wanted to drop everyone a quick note about reviews. For the next few weeks, I will be unable to review products. I am happy to coordinate new ones, but I am moving across country soon and everything important (like my camera and computer) are getting packed up. And this place is now a mess. This should just be temporary and I hope to be setup in my new location soon.
