DIY Push Pull Tube Amp Build

at 6:14 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

This DIY Push Pull Tube Amp Build doesn’t need a circuit board since everything is done using point to point wiring. If you open up some old equipment such a TV or stereo you will see that this type of wiring was the norm. It is hard to believe that this was the way mass produced equipment was constructed.

"Initially I started with 6EU7 tubes in the preamp stage but later switched to 12AX7A tubes as they are easier to find. I only have two 6EU7 tubes and I feel I should save them for another project. The 12AX7A heaters are powered by a separate transformer. I also chose to rectify and filter the heater supply to help further reduce the chance of hum in the preamp stages. Here is the 6T9 Push-Pull Tube Amplifier Schematic I came up with. "
