semi-related. People who build tube guitar amps (lots of high voltage AC) take component placement very seriously. The magnetic fields floating around the chassis greatly affect tone (and noise, which is sometimes a big part of tone.)
Some of the high end amp builders I know have spent a lifetime of experimentation figuring out the best way to place components and route circuits [anecdote, no references available]
If you want a simple example, have a look inside any audio amplifier. The two transformers will always be mounted at a 90 degree angle to each other (power xformer/output xformer) to minimize noise.
- aarongough 16y agoYes indeed. I have actually built a few tube guitar amps for fun. I did the designs myself and the first one produced so much noise/hum that it was practically unusable. Twisted pair wiring, careful routing of grounds, transformer location and component selection all seem to play massive roles. No wonder then that most amps these days are built around transistors, even though they sounds worse...
