WebNo current flows ‘into’ the heater supply from here, so the power valve bias is not affected. Dropping Heater Voltage The heater voltage should be kept within +/-10% of its nominal value for optimum valve performance. For 6.3V heaters that means 5.7V to 6.9V, though it is even better to stay within +/-5% if you can (6V to 6.6V). WebHome Electro-Harmonix
