I hate to ask such noob questions, but honesty, it's difficult to find answers to the simplest questions when just starting out on a tube build.
I'm building the S-5 K 16LS. It's a very simple build. I'm gaining knowledge and realize that I can't just blindly add additional switches and the like without considering interference. And if I'm correct, the main source of interference is with the AC side of the house - hence, I'm twisting wires from the PT and trying not to make any major changes. However, I wanted to check with all of you on the following questions:
1. I'm only twisting wires that carry AC going into the PT from the board and the secondaries from the PT going back to the board. I'm also twisting the wires going from the OT back to the board where they connect to the speaker plugs. I didn't bother twisting DC side of output transformers. Is this correct?
2. I'd like to incorporate an IEC plug, fuse, switch, and power light. How do we do this while minimizing interference? Or are we only concerned with interference from the PT secondaries to the board?
3. Is it okay to relocate input signal connectors and volume control (pot) without worrying about interference since it is DC?
4. I've mounted my transformers (all three), below the main circuit board. There is a large electrolytic capacitor I'd like to relocate. Is it okay to just run jumper wires from the board to the capacitor, or are there considerations that I might not be aware of?
5. Finally, because I did mount my transformers below the main board in the chassis, I was thinking about adding a fan for cooling - will this cause interference?
I realize that this is a tall order. Any help would be appreciated!
Thanks
