I use my P300 as a voltage converter for my Garrard 401. 60hz in and 50hz for the turntable. A problem has occurred where, when I turn it on of power it on, the “5 in” flashes momentarily and the red led in the upper left of the display is illuminated. The mode does not function at all and I get the same “5 in” on the screen and what sounds like a relay makes a clicking noise. If I hold the mode switch down the same screen message flickers on and of and the clicking is continuous, all the while the red led stays on. Can anyone give me insight as to what is happening and if the situation can easily be repairable? The unit has been operating flawlessly in this capacity as a voltage converter for over 15 years. I haven’t used any of the other functions of the unit. It sees only the current draw of the turntable motor. THANKS for the assistance!!!
