Was thinking about adding input and output transformers here and here. Ordered some Tubetech transformers from a US vendor. TR230 and TR242 input and output transformers. Lundhall conversation, told me they are similar to their 1540 and 1585 transformers. Which I will be purchasing in the future as well :).

Not sure what the impedance/specs are yet, but hopefully going to update this with some measurements (gonna read some chapters in the Art of Electronics book) and (friends from here).

If my assumptions are right, they should be ok being plugged in to these sections. If plug and play, maybe I can make a xfmr box with trs connections for easy jacking.
