Is this full voltage or like uTracer short pulse. Is the Gm from database or calculated? |

The GUI is a special newer version of utMax (which is open source), and it has modeling (modeling currently needs to be fixed though) for better Gm readings based on operating point. |

I would definitely be interested in building one of them! -Pat |

My tube amp forum obviously has interest too. I'll need to buy more PIC chips before I can sell more than...2 lol. But also, unless you have a stockpile of convenient parts, a lot of the parts on the BOM are backordered until next year. Yay for covid supply chains. 🙄 I'll eventually build a website with build info and share the link here. How are you with SMD stuff? There's a few tiny things on there. 😉 Thanks, Josh |

And yeah, the supply chain is a total clusterfuck. Been dealing with it trying to get parts for work - it's crazy. Stock expected six or more months down the road. On things like Molex Connector housings. WTF? :palm: -Pat |
