Q Bias for Cary SLI-80

Cary co. says that proper bias for Cary SLI-80 is about 75mA.

But the allowed range of bias is from 75mA to 100mA.
Which one is the best from your experience?
I would share our information.

And, I heard that I can use EL34 or 6L6 outpu tubes instead of KT88/6550 and when using other output tubes, it should be same bias.

Is it right? If anybody knows it, please share it.

hi,

I've used KT88's ( EH and JJ Telsa) and 6550's ( Tung Sol nos solid gray plates, and Phillips nos ) biased at 75 with good sound. The favorites of mine are the JJ's and Tung Sols.

I tried EL-34's and , well they are in a box and the Kt-88s are in the amp.

good listening,

Larry
