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.

Thank you very much.
Good information!

Then, is it same bias for EL34, 6L6 like KT88?
(range is from 75 to 100 mA, right?)

I have already sent email withsame questions to Cary Co.
But they have few information for that. (I think they are lazy to answer it.)

Thanks !

emailing cary yields hit or miss responses. actually pick up the telephone and call them. you'll get a lot more information this way.

Personally I liked the EL34's, biased higher (90 to 95), in my SLI-80.

Thank you, Rrsclyde!

Good information!
If anyone uses 6LL on the SLI-80, please share it.

I tired EL34 on my SLI-80. EL34s are Antique Selections EL34 JJ Tesla Blue Tubes.

I adjusted bias as 90mA.

Sound is firmed up and more clear.
Very high sound is too musical, Bass is more tight!

It's big change! If you have SLI-80, try it.
