D-lab tackles 2 Dynakit PAS2 preamps. One is a customer unit, the other a swapmeet find. Both needed power supply work. These are aging electronics, approx 60 years old. The capacitors are always the first to go. I routinely update the power supplies with my PAS Plus boards. These boards replace the entire power supply post transformer conditioning. Plus have a on board fuse to protect the main power transformer and relay to switch the high current on the rear switched outlets. As you can see, its a drop in solution. Fairly simple to install. If your interested in one, drop me an e-mail or visit d-labelectronics.com. I also offer a complete installation option with a overall check/test of your preamp. There's nothing as grand as the sound of tube audio! BTW: This board will also install into the PAS-3 series. See my other videos featuring the process.
