New guy sayin' HI.

I picked up this Crate Flexwave 15R for $30.  The input jack was jacked, so I got a new one and got out my T-rusty soldering iron and soldered the new one onto the the PCB.  Yay Me~!  It worked!

I was hoping the bad jack was the culprit behind the loud hum and radio station noise.  It was not.  I have one of those cool magnifier + circular bulb on spring loaded arm lamps and a careful inspection by my untrained eye did not reveal any obvious problems.  Nothing burned, nothing leaking, nothing swollen and no bad solder connections that I could see.

So here are the symptoms.  Radio station pick up is minor, but the hum is pretty loud.  It makes the hum with or without guitar/cable plugged in. The gain/volume knobs do not affect the hum in any way I can hear.  The hum loudness will vary greatly dependant where I stand and how close I am to the unit.  When I position the power cable in a certin way, the hum all but disappears.  In this position I have to strain to even hear it.

I'm attaching a photo, for what its worth, and I posted a schematic for the amp in the schematic section.

Any thoughts are greatly appreciated, and your threshold is very low if you allowed me to become a member :cheesy:
