Many of us aren't native English speakers so don't worry about your language, we all make mistakes
With ongoing participation in English lnaguage forums your language skills are likely to improve !Back on topic: can you post more details about output transformers (number of turns etc.) used in your amplifier ? These are usually the most expensive item in tube amplifiers so I'm curious how you managed to keep the cost at $50.
Thank Arnulf.
My Output transformer used EI66,pri 10K(2.5K-0-2.5K),second 8 ohm.
Number of turns pri : 1600T x 2, wire 0.18mm
Number of turns sec: 90T cheap 3,wire 0.5mm.
Ultra low cost by tube $0.5/1pcs, PCB two layer $8/1pcs( 24x32 cm),chassis $3.5,OPT EI66 $3.5,Power trans $3.5...
My design schematic and PCB,resistor,capacitor...very low cost.
