Input resistance is very high but differs in CM and DM and depends on frequency, so what value do you want.
I' puzzled why you need a trafo, is there some large chassis voltage to bridge?
When that is the case and you definitely need a trafo, you better place a fixed resistor on the secondary side between 10k and 100k.

Still no sign of my board which arrived in Canada less than 24 hours after posting in the UK.

After countless hours on the phone to both Canada Post and Canada Customs, navigating menus that are designed to make it almost impossible to speak with a real live person, I managed to confirm that my board is 'probably' at the Vancouver Customs Clearance facility and that they are currently experiencing a turn around time of up to 46 days!

It seems a shame that for all the effort that Xavier went to, to be undermined by Canada Post and/or Canada Customs - one has to love the unions!

Thanks to Canada Post having taken well over two months to deliver my board, and despairing that I ever would receive it, I started constructing a different preamp instead.
Which means, that the assembled group buy board I now have in my hands is surplus to my requirements.

I am willing to let it go for exactly what it cost me $61.50 USD plus postage (which I can quote on when I know the intended destination) to the first person to respond. Payment via PayPal only.

Thanks,
Clive
