This is the amplifier frequency response at 20W into 8 ohms load, with zero feedback.

I used Tango NC15 (the white one on the right) , mounted underneath the chassis.

I dont want to use input transformer because you will need a preamp with 600 ohms output. Also good quality input transformer is expensive.

You must have a nice stash of Tango transformers

IMO good input transformers are quite a bit cheaper than the going rates for old Tango IT/OPT. Cheaper than the good Tango ISO as well.

I have not tried many input transformer (600: 15K-20K), but I did tried some UTC A11, LS151, and I prefer Input gain stage with tube. There is always pros and cons, unless you have a really good input transformer with great bandwith, and a low impedance source to drive it, I think input tube has advantage, yes tube does adds its own coloration, you have to choose one that matched your system, but it will sound more dynamic than any passive device.

I guess Tango is shutting the door for good this time!

This 2013 year is being awful for many persons and companies, except banks.
More one year of crisis.

Any idea why they are shutting down?

I did put an order for Tango 2 weeks before shutdown, they did not take my order.

That was Sep 2013, Tagon ISO closed their doors. March 2016, after two years and a half, I received the first new Tango transformers from Wavac and design them in my WE21E mono block amplifiers. It's a GM70 driving we212E amplifier.
