B1 buffer DC at output

[blehmbo]

I originally posted this in another thread and it quickly got buried, so I will attempt to repost it here.

I recently completed my B1 build and I was wondering if it's normal to get fluctuating DC at the output (measured across R105 and R205) with music playing through it. With no signal running through my B1 the offset is steady around 5mV, but if I hook up a CDP and amp and play music the DC fluctuates to around 40.

I am using a 24v regulated linear power supply that is rated to put out 300mA if that matters. All components have been checked for proper placement and no cold solder joints were noted.

Thanks in advance
