Tank's DIY tube preamp
a few weeks ago i posted here, questioning the quality of the ebay tube preamp kits.. and the results were mixed. after much contemplation i decided to give one of those kits a go after reading some good review about it - and im super happy i did so!!
This kit is a a super simple buffer tube preamp board with a 50k pot, and it also came with a transformer. the kit uses two 6n3 tubes, which were also suplied. after listening to it for a while i decided to give it a proper enclosure - and this is the result:
when i first approached this project, it was important for me to not just build a simple enclosure based on existing designs, but rather start from scratch on try to thing both on the looks but also on the manufacturing process - keeping it as simple as possible.
first of, i started with the three aluminum sheets. i marked everthing out, and made the first cuts in the board:
the next step was preparing all the wiring:
then i took things to my schools workshop for the building of the enclosure itself:
once all the holes were made, the wood was varnished and the welding began:
and once everything was hooked up:
at this point im 99 percent done, and other then a small shielding problem in the selector switch (which i will attend to shortly) everthing works great, and the sound is exactly what i was looking for when i first decided i want a tube preamp! bang for buck - this is one of the best deals i did in the audio world :D
so, what do you guys think? i did good? any suggestions for improvement?
Well, you're listening to Joni during one of her better periods, so there's not much room for improvement.
:cop: Moved to Tubes / Valves on the premise that this thread would get more visibility here.. :D
great work man! What size brass standoffs are you using, M3 or M2?
