I am using an input transformer between my DAC (r2r, 625ohm impedance, 1,8Vrms output) and the first tubestage which is fixed bias through the secondary of this xformer. It works pretty well.
When comparing input xformer specs on Aliexpress...I constanly ready max signal current ?!? What does this mean ? For sure not DC current...small devices, no airgap etc.
