Visit www.milleraudiollc.com for more information Miller Audio LLC Introduces the new Dynaco ST-70 / Dyna-70 Ultimate Upgrade w/ Manual Bias The Dyna-70 Ultimate Upgrade with Manual Bias is the original version of the Dyna-70 Upgrade kit, introduced approximately 5 years ago. There is no difference in the power or audio circuits between our Manual or Automatic Bias versions; they both sound superb when compared to a stock ST-70, or any other ST-70 audio circuit only upgrade. The Dyna-70 Ultimate Upgrade is just that- it ultimately it blows all other ST-70 audio upgrades away. The Dyna-70 Ultimate Upgrade is based on the 6CA7/EL34 family of power tubes, just like the original ST-70. If you have a good set of 6CA7/EL34 tubes in your ST-70 they will work just fine with the Dyna-70 Ultimate Upgrade. The Dyna-70 Ultimate Upgrade Kit features these performance benefits: Kit Assembly Kit construction has four steps: Downloading and printing the latest version of the Dyna-70 Ultimate Upgrade Assembly Manual (www.milleraudiollc.com) Populating and soldering kit components into the supplied PCB. Connecting the Chassis & PCB Wiring Mounting the new PC board(s) and completing wiring & final assembly, setting bias (Manual Bias Kit) The Dyna-70 kit features all through-hole components. The electronic circuits are built on high-quality, etched 2-layer FR-4 Copper faced Printed Circuit Board with plated through holes for generous solder contact and easy soldering. The circuit boards have been designed with generous spacing between all the soldered points, making assembly easier and reducing odds of a solder bridge. We use quality, name brand components from manufacturers such as Nichicon, United Chem Con, Panasonic, Wima, Solen, Audyn as well as 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 counterfeit parts. If your budget doesn’t have room for the Auto Bias version (listed elsewhere on eBay) of the Dyna-70 Ultimate Upgrade, don’t worry, while you still have to manually adjust bias, likely you’ve done it for years with your stock ST-70 or perhaps a competitors driver stage PCB. You will still experience the fabulous 3 Dimensional sound stage and stereo imaging from your “Ultimate ST-70”. Yes, its an expensive upgrade, but the Dyna-70 Ultimate Upgrade isn’t only an audio circuit upgrade- that is frankly the less expensive section to upgrade in an ST-70. It is more expensive to upgrade and improve the Power Supply system and that accounts for much of the additional cost as well as improved sound qualities. NOTE: This upgrade kit does not include 6SN7 tubes or the larger, improved PA-060 Power Supply Transformer. These are additional cost items required to implement the Dyna-70 Ultimate Upgrade into a Dynaco ST-70 amplifier. Visit www.milleraudiollc.com for more information
