Looking to boost my 12v relay


Hi -

I have a 12v trigger from my preamp to my amp.

Problem is that the preamp outputs 100ma and the amp wants to see a minimum of 110ma.

Wondering if anyone can recommend something to boost the output of the relay - ideally it would be 3.5mm jack in and out so it would be inline with the existing connections. Could be battery or AC powered

Turning the preamp on will turn the amp on. Turning the preamp off will turn the amp off.

thank you in advance for your assistance

best,
ck

I doubt the extra 10 ma will make a difference to the preamp. You could measure the DC resistance of the amp trigger input and verify how much it will actually draw at 12 volts.
