Hello, I would like to share with all of you, DIY builders, my project based on KT77 and 12AX7 tubes.
Nothing special (SET have been on the field for 100 years) but it may contain some interesting solutions, like a selective band global negative feedback, ultra path capacitors, back-to-back capacitors, plate-to-plate inverse feedback, a complete simulation through LTspice, schematics measurements and mods of my audio chain etc...
May be here we can exchange some comments and few extra ideas.. :beerchug:

Hi GG - welcome to the forum. The amp turned out real nice. I also like the work you did on the NAD C525bee.
