We now offer a PCB assembly service where for $185 we will assemble and test your Dyna Audio/Power Supply Drive Card, saving you time and trouble with a properly assembled and tested Circuit Card Assembly.

Dyna-70 / -120 Ultimate Upgrade Kit / For Do-It-Yourself (DIY) Hobbyists Our kits feature all through-hole components; the electronic circuits are built on high-quality, etched 2-layer FR-4 Copper faced Printed Circuit Boards with plated through holes for generous solder contact and easy soldering. The circuit boards have been designed with generous spacing between all soldered points, making assembly easy and reducing solder bridges. We use quality, trusted name brand components from manufacturers such as Nichicon, United ChemCon, Panasonic, Wima, Solen, Audyn and other name brand components. We source our components from Mouser, Digi-Key, Newark, and other reputable U.S. suppliers; you can trust all components are genuine and not cheap counterfeit parts.

Kit construction has four steps: 1. Downloading & printing the latest version of the Assembly Manual 2. Assembling and soldering the PC board 3. Wiring the Chassis 4. Mounting the new PC board and completing wiring & final assembly

Note: Kits do not include vacuum tubes or the required higher output Power Supply transformer. See our website, we stock and sell vacuum tubes and the improved transformer separately
