TU-8500: Find the bug (found/solved)
I have proudly finished my first build ever – the Elekit TU-8500 tube pre amp.
I consider myself ”pretty good” at building things, but reality bites and truth hurts: I only have sound in left channel. I realise I need help so I will post my debugging here. Please feel free to help. But I warn you, I’m a graphic designer, not an electrician, so my questions will be stupid, ok?
So far, I have:
My plan is to resolder parts on the right channel starting from Jack 6 (pre out).
I have a multimeter but I don’t really know how to use it.
I plan to post pictures.
Help wanted!

So far, I have:
- Tested input from all line in and the phono in.
- Changed cables in and out and also changed power amp.
- Switched tubes from left to right.
- Gone over the manual step by step.
- Resoldered and switched between Jack 6 and Jack 2.
- Checked for bad solder joints. I’m new, it feels like looking at the Death star.
- Ordered a new soldering iron (who knows, it might help).
