PA34B is a monoblock amplifier that provides 80W output power. The circuitry is basically the same as for the critically acclaimed PA12 but further developed to effectively control 4 output tubes.
The current capacity is twice as high as in PA12, PA34 fits well with more demanding loudspeakers.
PA34 cuts soft and fine as it approaches the maximum power, even at 100W output power distortion is less than 3%
PA34B version has balanced input with XLR connector and can also run unbalanced via RCA input.
