My tiny newborn amp will not be alone. I will add a low voltage tube buffer as a nice companion. I just finish the module today. Powered by Russian 6N1P tube and Russian K40Y capacitors. Some of the circuit inspired by my colleague, AW from Tubelover Indonesia.
Under the table, we can see some mediocre components, like Takman, Roederstein, and vintage Vishay S139 Bulk Foil resistor. Tube buffer is a simple application, just 3 resistors and 1 capacitor, then you are done. We can do point-to-point without any problem. The filament would be AC and I hope there will be no problem forÂ it.
Later, I will power it up to see how does it perform.
