The input wiring section was intense!

Managed to complete it though. All the resistance and voltage values checked out so I hooked it up to my Roksan K3 amplifier and started playing music through it  :D

Thank you everyone for the guidance throughout and helping me make my first tube amp kit a success!

May I ask what the balance knob is for? In what instances, besides DJ-ing, would one use it to make one channel louder than the other? This is the first time I've had a balance control at my disposal and it's giving me anxiety because I don't know if I've balanced it perfectly equal between left and right channels  :o

Four reasons for a balance control:

1) amplifiers without feedback may vary in gain by a few dB due to varying tube parameters.

2) room acoustics may enhance one speaker's loudness over the other

3) for diagnostic purposes you may want to listen to one channel alone

4) typical volume controls can deviate from matched gain, especially at low-level settings

I'm sure there are more, these are just what comes to mind this morning.

Thank you everyone for the guidance! Will do my best to balance the preamp using tracks with a strong centre image :)

Again, nice clean build and finish. I noticed that you are using directional RCA cables on the output and that one is reversed. Will the electrons be facing the wrong direction in that channel?
Enjoy the tunes.

Hah thanks @Karl5150 for pointing that out! In my excitement to listen to the Moreplay, I didn’t realise I had the direction reversed  ::)

Received plates with labels for the knobs from Andre (username AG) and they look great!
