screen grid in bulgaria - gnomiki.info
2020-5-30 · internal screen grid capacitance. The value of the final tube’s screen grid RF shunt capacitance is the primary audio frequency limiting factor in a SGM circuit. Therefore, it is important to keep the total screen grid circuit capacitance at less than 1000 pF, for a shunting impedance of approximately 45 ohms at the lowest ...
