[QUOTE="Oregon, post: 140878, member: 3141"] Someone jump in if I'm wrong, but I've never heard of biasing preamp tubes. I don't think that's an option. The best way to change the preamp tubes gain is to swap for a softer tube (like a 12AT7 from a 12AX7.) Here is a chart that indicates what preamp tubes can be easily swapped: http://cydathria.com/fdm/12AX7_sub.html (the 5751 is a military designation in case that difference is confusing.) Also this isn't all the preamp tube options. Try reading up here (good source for brands and types.): https://www.tubedepot.com [/QUOTE]
