By request! The Granger OptoFET Daughter Board works with our popular OptoFET Channel Switch Jack, when more than one DPDT switch function is needed. Simply mount it using the included standoffs (or your own), and run jumpers from the + and – terminals on the Channel Switch Jack to the Daughter board, and you’ve got double the relays.

The OptoFET Daughter Board can also be used as a stand-alone DPDT relay (2 sets of NO/NC contacts) when supplied with 5-8VDC power and current limit resistor. Just provide your own switch (front panel or footswitch/jack). And since it is solid state, there is never any switching noise, provided your audio signals are properly decoupled from any DC source. Switching time is extremely fast – nearly instantaneous.

Our real world test showed the Daughter board ICs run 12mA each (24mA total) using a 6.8VAC supply into our 5V Regulated Supply, through a 100 ohm 1W current limit resistor, so current demand is extremely low.

PLEASE NOTE: This product is intended to be used with our OptoFET Channel Switch Jack [CHANSW-1] . If using as a standalone component, user assumes all liability in properly powering unit, including placing a current limit resistor in series to source. Values from 100R to 220R will suffice. User assumes all risks in using product in this manner.

DISCLAIMER: User assumes all risks. Performing these modifications will most likely void the warranty on your amplifier. Working on amps can be deadly if you do not take proper precautions. Basic soldering skills and basic user-supplied tools are required. If you are at all unsure of your ability to perform these modifications STOP and take your amp to a professional to be modified. You can also send your amp to us for modification. Contact us for pricing.

DIFFICULTY LEVEL: INTERMEDIATE [Follow safety guidelines for working with electricity. Basic soldering skills and knowledge of working with AC/DC circuits. Identify all terminals of electronic components using data sheets. Read resistor color codes and capacitor values. Measure and connect high and low voltage AC and DC. Understand basic working of vacuum tubes. Use all functions of a multimeter. Understand Ohms law and apply to basic circuits. Work with basic hand and power tools.]
