MODIFYING THE PHONO INPUT

This is for those of you who don’t want to use the phono input, but would like to have another LINE input. Follow these steps and you will then have another line input! Don’t destroy your parts taking them out since you may want to re- install them later.

1. Remove R57, a 180 ohm resistor. (brown-gray-brown)

2. Remove C16, a .0033uF ceramic capacitor (marked .0033 or 332).

3. Remove R67, a 180 ohm resistor. (brown-gray-brown).

4. Remove C22, a .0033uF ceramic capacitor (marked .0033 or 332).

Now the PHONO amplifier only will have a level flat gain of 1. Now you can use it for another line level input.
