Elekit TU-8200R Stereo Tube Amp Kit

Hello All,

Hope all is well with everyone during this pandemic. I just joined the forum and this is my first post. I bought an Elekit TU-8200R Stereo Tube Amp Kit from TubeDepot online and should be getting it probably next week. This will be my first DIY tube amp kit. I like to listen to music and would like to get the best sound out of this Tube amplifier. My goal is to replace the stock 6L6GC and 12AU7 tubes and coupling capacitors. I need your recommendation to what brand of vacuum tubes is the best and coupling capacitors to get the best out of this amp also are there any other like resistors and electrolytic capacitors on this kit that I need to upgrade? The source I'll be using is the analog output of Bluesound Node 2i and EVGA Nu Audio sound card that has Burson V5i-D opamp and connect it to the 2 inputs of Elekit TU-8200R amplifier. Also what kind a speakers you recommend to pair it with this amp I only have an old Pioneer SP-BS21 bookshelf speaker. Your help and advice is greatly appreciated.

Regards,
Jerry
 
Carefully build it first. Get it up and running.
Listen to it on the speakers you have.

You may be surprised by the good sound.

After all that, think about changing something, like caps, tubes, etc.

The first rule of modifying any thing is to get it working well first, and then change something.
Changing two or more things at once does not tell you which change did anything, or whether the two changes cancelled each other, one made it worse, etc.
