Luxman L-308 bias and DC offset

Recommended Posts

Hi folks,

 

I'm restoring a beautiful Luxman L-308 integrated amp which is working but sounding a little too warm for my liking.

 

Looking for any experience on what the correct bias voltage should be across the emitter resistors please.

After warm up, I'm getting around 16mV bias and around 0.3mV DC offset on the power amps. I have only been able to locate a schematic but no service manual, so a little stuck.

 

Any pointers gratefully appreciated.

 

Cheers,
