Old devices shall repeatedly powered on from time to time, to hold the old elektrolytic formed. If this is not done, the forming current at power up may be extremely high an the elco or the rectifier tube may be demaged. Old devices from Ham shall be slowly started up with a variac, within some minutes. | |||
