The relay drive is removed in less than 25ms with the values shown – the relay itself will short the outputs typically within 30ms after AC is removed. They do exist, but are far less common than normally open contacts.

The same process can be used for any other zener voltage, but do not go below 5V or above 15V – any value you have handy that’s in between those will be fine – but only for a genuine B or direct equivalent, such as 74C Have one to sell?

Should the AC fail or be switched off, C1 charges rapidly well before the preamp supply voltage collapsesand there is nothing to prevent this U1A is not pulsing low any more. There are 5 items available. In addition, nearly all opamps are protected against shorted outputs anyway. Connect to a suitable power supply – remember that the supply earth ground must be connected!

In some cases, it will be necessary to add a resistor R8 in series to obtain the correct operating voltage for the relay s. Verify that the relays are connected properly by measuring with an ohmmeter – the preamp etc. Without it, the relay state will be indeterminate at power-on if nothing is connected to the AC terminal.
