Cary SLI-80 bias voltage

I just purchased a used SLI-80 integrated amp, and am wondering if anybody out there knows the correct bias voltage for the stock Svetlana 6550 output tube. Also, since the triode/ultralinear switch is unlabled, can anybody confirm that the "up" position is triode mode. Sure sounds like it.
Thanks!

P, straight off the Cary website, the correct bias voltage for the SLI 80 is 75-100MA per channel. While 75 MA will preserve the life of the tubes, 100MA will sound a bit sweeter. I am unsure of the switch position, but the louder position will be the ultralinear while the triode position will sound sweeter and more three dimensional. Hope this helps

No problem, P. If the amp clearly plays louder in the down position, that is indeed the ultralinear mode. Enjoy your amp. Cary makes wonderful products.
