Note: Due to the mass production procurement reasons, the components of each batch are not guaranteed to have the same shape, but the quality is guaranteed.
The input AC voltage is about 10V-80V, and the adjustable output is about negative 10-80V.
This is an adjustable negative grid voltage circuit board for the tube power amplifier, Single-ended and push-pull all can use. which can make each power tube work stably and balanced
