Miller Audio LLC ( https://milleraudiollc.com/ ) is re-introducing the Dyna-70 Ultimate Upgrade for the Dynaco ST-70 to the DIY audio community. Several years ago Erhard Audio introduced the Dyna-70 Ultimate Upgrade. In our testing and listening trials, we concluded that the Dyna-70 was the best of the ST-70 driver upgrades that are in production and available today. We built and integrated a number of Erhard Audio Dyna-70 Ultimate Upgrades for our ST-70 customers. The Dyna-70 sounds so good the kit sells itself once you hear one.
The Dyna-70 Ultimate Upgrade is different than most ST-70 driver updates offered today because it isn't just an audio driver upgrade, its also a power supply upgrade. In fact, the truth is a Dyna-70 is a more expensive upgrade than just replacing a driver CCA, and it provides the ST-70 something it has always needed- more power and filtering. The Rectifier tube and multi-section cap can have been replaced with on-board, solid-state rectification and a minimum of 2-3X of additional filtering capacitance. It also features an on-board in-rush current limiter (ICL) with a 2-stage warm-up cycle for the signal/preamp tubes to come up before the output tubes, minimizing warm up noise. The Dyna-70 Ultimate Upgrade now comes in two configurations at different price points: Automatic Bias or Manual Bias.
The Dyna-70 Ultimate Upgrade is now available and in production. Visit https://milleraudiollc.com/ for details and contact information. We offer a full selection of NOS 6SN7's, as well as a comprehensive selection of new production EL34 / 6CA7 tubes, and film coupling capacitor upgrades from Mundorf and Solen. We also offer the Dyna-70 bare PCB for DIY'ers in both auto-bias or manual bias configurations, allowing DIY'ers the ability to pick their own parts or experiment with various components.
Miller Audio LLC will be demonstrating the Dyna-70 Ultimate Upgrade at the Lone Star Audio Fest, June 2-4, 2023 in Dallas, TX at the Embassy Suites Hotel, Dallas Galleria,
14021 Noel Road, Dallas, Texas, 75240

We welcome everyone to stop by and listen to some of the best sounding ST-70's you'll ever hear.
