Is the Suma 310 Polaris a true class A A/B amp?
Does anyone have a service manual for it?
Thanks

Is the Suma 310 Polaris a true class A A/B amp?
Does anyone have a service manual for it?

From the user manual:
"The new Sumo Polaris class AB power amplifier banishes transconductance error completely with exclusive power MosFet correction circuitry."
It's doubtful that a Sumo service manual is available.
