That's the case. I used to bias vintage Mullard EL-34 tubes at 60-65 mA but soon replaced them with GEC KT-88s. First I biased the
GEC tubes at 75mA as recommended but did not like their sound. Now they are biased at 65 mA and sound much more open and transparent without being bloated.
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.
