Till now I made Jensen 1071 Speakers (of Troels Gravesen), Lampucera DAC (DAC kit from HongKong mod. by Lukas Ficus), BoozhoundLab Pacific Phono Pre, so I had some soldering skills without detailed electronic knowledge... All were figured out from manuals of parts...
Finally week ago, I have completed my SP 14. Due to high transportation cost to Turkey, I supplied from Roy, PCB and its components. Hereby I have to thank to Roy. During all my DIY background, I had correspondances with many suppliers around World, Roy was the most responsive of them. He answered to all my questions (may be even to some silly ones , as its my first complicated project ).
It was a week I have completed , left channel was ok but I could not get sound from right channel. Later I figured out, that I have soldered signal cable and ground shifted. Then I controlled it is ok.Now just at the beginning I have very tiny deep crackles at right channel, which goes after warming up.Then deep silent kit.
