Happy New Year All!
Currently working on finishing a couple of Tube DIs. Also thinking about bringing back the Gemini Twin 45/2A3. Also a new 300B amplifier is in the works. I know finish the phono stage and preamp :)

Hey everyone it's my BD today and I figured I better update what I have been doing. So I should have a Tube DI called the Cube DI because of it's shape and a pedal sized SS DI called the Direct Injection NGEN. But I found 2 sets of mono block chassis here at the office in the basement. Don't even remember making this size but they are mind condition so.... what to make. I will have 2 only Fully MagneQuest Iron, custom Silver Parallel feed amplifiers to sell soon. 6.5x12x3+Tube height. What tubes should I make in it?

Been playing around with some of these AC to DC switching power supplies. This one has a filament supply that comes on first and is very low noise. Then the HV is ramped up about the same speed as a 5AR4/GZ34 rectifier (about a minute). First up is a 12W 6AQ5 (smaller version of a 6V6) PP amp using a center tapped inductor as a phase splitter. A single 12DW7 (1/2 12AU7 driving the phase splitter, 1/2 12AX7 providing the input gain). This amp is killer super low noise. Also about six pounds lighter!
