QUAD 405 Lower input sensitivity to 1.5V

Chaps,

I bought this 405 which was overhauled about two years ago and is working wonderfully. All electrolytic and ceramic caps have been replaced with higher quality electrolytic and film capacitors, it was also completely rewired with thicker wires for better current carrying in the power supply and output lines, and with audio type coax cables for audio signals. The op amp ICs were replaced with Burr Brown audio quality op amps ICs but the input sensitivity has been left unchanged.

What cap or resistor do I add, value and where to solder it?

Thanks much in advance.
