Transformers "color" box wiring check

fazeka · Apr 27, 2018

All,

Need your advice.

I want to have two different types of 1:1 isolation transformers. Was thinking it would be interesting to wire them up with the most flexibility. In series (with differing orders) or alone, with differing secondary impedances. Including a bypass and a polarity switch. Schem is attached here.

What do you think? Do I have this wired up properly?

Cheers,
Chris

I've never tried wiring an input tx into another input tx directly. How's it sound?

i built a box like this with 4 transformers per channel with individual bypass and order switchable.

They are highly interactive in a very interesting way. All wired 1:1 to 1:1 without issues

I also installed a couple of rotary switches to modify caps and resistors values (zobel network) right at output connectors

It works like a charm!

I built mine using relays, totally recommended:

Fixed the diagram. I forgot a bridge from one set of poles to connect the output of xfmr B to the output (position 2).

Any thoughts on grounding? I was going to run from the input a shielded cable with the conductors to a ground lift SPST switch and then carry the shield on to the shielded cable towards the output.
