Many thanks for you welcomes ! Buongiorno is the right spelling

As mentioned I was looking also to AK forum because I'm manufacturing two mono tube amplifiers 300B single ended and I had some doubts about right ( or best ) connection of the CT wires of the tubes filament supplies
( rectifier and 300B tubes ), I discovered how to do it now. Power transformers, chokes and output transformers are from Hammond, 300B tubes are Svetlana.
About my gears, I have, I have a lot,,,,,, ( ask to my wife

). About music I love also vinyl, my turntables are Project Debut, Dual 1225, Dual 1216, cartridges Shure and Goldring, preamp Schiit Mani, amp Marantz, loudspeakers Advent 5002
double stacked.
I like sometimes also to play music, I have an Hammond A100 from Chicago built 1964, a Korg arranger, a Gibson Les Paul and a Martin acoustic.
Above only about music, I don't speak about photography and other hobbies.......
So if you all need some help or info, just ask.....
