So when I learned that Classic Tone was folding I though I would buy some Iron for a build. I decided to build a Harvard 5F10 to be able to see/hear/experience the differences of the 5E3 Deluxe. After reading through a couple Harvard build threads, I decided to 1) use a Princeton Chassis and drill xtra holes, 2) use a 12A*7 for V1 rather than a 6AT6, and to 3) try a Hoffman board for the first time. I bought a 40-18021 for the PT and a 40-18023 for the OT. When the Chassis and Trannies arrived, I realized the PT was bigger than the hole in the Chassis. So I “modified” the chassis for the PT and drilled the xtra socket holes. This will be my first “Fixed Bias” build. Since the PT does not have a 50v Bias Tap, I will need to figure out how to tap into the 5V Rectifier pin. Also need to figure out what B+ voltages to shoot for. Open to advice and suggestions here! Also, if you have built a Harvard, what do you wish you had done different?
