Doc![]() | Re: MB Mark IV Power Tubes All we have to do is measure the plate, screen, and grid bias voltages, and the idling current for a set of mesa sanctioned tubes in various mesaboogie amps, then we'd know what parameters are required to be matched in the tube suppliers' tube test rig. A few suppliers match power tubes at realistic circuit operating voltages for a guitar amp anyway. If we could get them to adjust the voltages accordingly, they could supply the tonemongers with really good plug-ins for mesa amps. Same deal with GT's. How about a general correlation in ratings of transconductance and plate current (as labeled on tested matched tubes) with the typical 1-10 /soft-hard GT rating? No patent infringements here. |
