I wanted to give the Dynaco a facelift, without turning it into a completely different amp (ie modded driver board, inputs/output connectors, or completely different power supply circuit.) So, I've been accumulating bits and pieces for awhile and started on the project this week.
Cap voltage points were tested, all resistors were removed and values checked, and then everything was reassembled on a new chassis that is authentic in every respect. All NOS hardware, input jacks, and speaker terminal strips went into the chassis. The PC-3 is a Vintage Electron, identical to the original, with better board composition and much better tracings and solder pads. I re-used all the original point to point wiring (again, wanting to maintain the authentic sound versus modern dialectric coating and silver plated "audiophile" conductor.) The only non-authentic components are the orange drop coupling caps, and a diode by-passing the selenium rectifier. I hope to have it pumping music by tomorrow, but took a break to show a before and after. It's been a wonderfully fun project. Like a vintage car, there's no better way to understand it inside out than a rebuild.
Edit: sorry for the large pic. Hopefully this one is better.
