Relay install tips for the 16 pin Relay and sockets

This is the schematic for the 16 pin small signal switching relay's that I stock.

Without any power to the relay coil, pins 13 and 11 are connected on one side of the relay.
On the other side pins 4 and 6 are connected

Applying 5 volts to the coil will connect pin 13 to pin 9 on one side of the relay.
On the other side pins 4 and 8 will be connected.

This is a relay power supply board.
The white wires are the 6.3 vac coming from the amps heater supply.
To relay coil +
goes to the relay coil positive.
The relay coil minus is what you ground with a switch to turn the relay on.
I used 4700uf/25V caps because that's what I had on hand.
I stock 4700uf/16Volt caps to use on these relay power supplies.
-
This is the schematic for the 16 pin relay that I currently stock.
The power supply board is shown above.
I have two 4700/16V filter cap and I have them separated by a 180 ohm 1/2 watt resistor.
The 180 ohm resistor drops the supply voltage to the relay down close to 5 volts.
Without out it I was closer to 7 volts.
You can adjust the value of this resistor to suit your particular amp.
