    Dgse1 ultra linear

    Hey everyone, I've built a couple tube amps in the past but finally ended up pulling the trigger on building a dgse1 since I've heard mostly good things and love the sound of the maggie 8601 I suped up. I changed a few things from the schematic but mostly just the power supply to adjust the...

    7868 or 7591 Push-Pull Ulta-Linear Design Help

    So here is a window into how my brain works. Step one: found a Bogen CHB100 on my local Craigslist for cheap. It had a quad of these. \/ (that's my attempt at a down arrow) These are 7868 power tubes. I've had a desire to build an amp in the 20-25 watt range so the hunt began. Looked up the...

    Decision Time: To Upgrade OPTs for Maggie 9304-20 or Not!?! Help

    For those who aren't following along, I'm amidst a console rebuild with a 9304-20 amp at its core. I'm working through a full console refurb, and it is time to either order upgraded output transformers or not. The idea from the beginning has been to go UL with the 9304-20 using new Dynaclones or...
