Dynaco Mark III tube audio amplifier Bias system update Selenium to 1N4007 diode new resistor values

Lots of mis-information floating around the web on this subject. Here is the solution, tested on the bench of D-lab electronics. I found many offering a bias kit, however none of them showed the installation procedure. I have tested the bias adjustment. Plenty of sweep to set the proper current. Yes, it is a good idea to replace the selenium rectifier. When they fail, its a nasty experience. If you need more info or the diagram, e-mail me.
