Have you cleaned up that board yet? I need to see it.

 

[HomerJSimpson]

What do I clean it with?

 

[avionic]

Clean that board up with alcohol or acetone.. I can't see anything with all that flux residue.

 

[HomerJSimpson]

Is this better?

FYI this unit has come stating out of protection before I replaced any parts on the power supply board.

[avionic]

YI this unit has come stating out of protection

What ? How does the unit sound ?

 

[HomerJSimpson]

When th unit is powered on for the first time initially, there is a good thump sound through the speakers.

Also I am noticing a slight hum on the right channel even less on the left.

Does the relay ativate immediately or is there a delay ?
