Questions about tubes and gear that glows. FAQ


If your Cronos Magnum operates the same as my Stereo 90 (and I think the amp sections are very similar), you bias KT120/KT90/KT88 at 35ma on the built in meter, and bias KT66/EL34/KT77/6L6gc at 30 ma.
Check with your manual or contact Rogue (great people to work with) if you are unsure.
