Hi fellows,
I'm doing what I think to be my last amp, the heart of the amp being a TA3020 kit from 41Hz. I had hard times finishing most of it with missing parts (another story) but now I start to get all parts in a spare lab chassis.
It's a modular chassis/case, so I plan to do sub-cases in, it will shield functions and boards nicely. If needed... overkill?
Anyway, I wonder how to settle my transformer.
Here are pics of the amp'n'DC sub-module (later with internal sub-sub-wall) and how I can physically fit the transformer. But I wonder if radiated noise/fields or such will ruin the amp, if the source selector's rod (aluminum) will carry nasty things directly to selector, sources wires, RCAs and line-level signals. I'll go for best layout possible to get the very best out of the TA3020 -loving how a friend's Truepath sounds-, and may find mechanical ways to deal with that. I can add walls in.
All comments welcome 🙂
Thanks,
Matthieu

I believe if the rod is electrically connected through the chassis at both ends then the transformer will cause current to flow through it, essentially like a shorted turn. You would just need to make sure one or both ends is isolated.
Hi,
So beside avoiding making a loop there is no harm having the transformer on its side facing the source selector. A plastic part between the rod and the selector and here we go 🙂
Thanks!
