By accident I found something strange with the amp I wanted to ask you about.

When I touch my fingers to the front input RCA shields and a speakers is hooked up I hear a loud feedback noise through the speaker and the amp draws a slight amount of current.

It does not do it through the rear inputs or the pass through inputs, only the front inputs.

I did replace the RCA jacks and both IN4003's, any ideas why it would do this?

Perhaps a defective 2/4 input switch???
