Hi
After that 6b4g project I decided to make one single ended pentode direct filament tube amp and in tow days project was finished . the sounds is different and I used this time ultra liner circuit so I needed one transformer with 40% of winding .5751 from use famous factory is best chose in driver tube so you don’t need negative feed back .
rectifier is 5z3 uk Made with gray plate and nice sound .
