    How should TR1 on the ’69 Stones board be adjusted? It doesn’t seem to be mentioned in the build document. Thanks!

    When biasing the Drain voltage it should always be about half of the supply voltage which is why you often see 4.5 – 5v bias voltages on many builds keeping in mind that nobody gets exactly 9 volts. This is a constant but I do see I need to add that to the build document.

     

    UPDATE: I updated the Build Document and two others that I found this week needing a few minor updates. Sometimes the (human factor) gets in the way and I might miss something but generally speaking I think we are in pretty good shape and a dedicated forum is always a plus when you are not sure.
