FIGURE 4.Simple schematic for a triode amplifier. C1 and C3 are DC blocking capacitors to isolate the AC input and output from the DC operating voltage on the grid and plate. R1 and R2 are the grid and cathode bias resistors, respectively. The bias voltage is developed by current flowing ...

Assembly Manual•Schematic•Parts List• Tubes and Applications At the time this manual was written,the Tubelab SPP has only been tested as a stand alone push pull amplifier. This means that a single SPP board is used with one power transformer and two output transformers to make a stere...

[Stephen McNamera] found a schematic for a grid leak radio online and decided to throw together a few tubes on a piece of wood and see how it worked.As you can seein the video below, it works well. The video is a bit light on details, but the web page he found the plans on ...
supply transformer on a mounting bracket and the board. I cut the board to keep the capacitors and rectifiers but reduce it's size. I removed the tube linear regulator section. If I had a schematic I might have kept it, but to reverse engineer it seemed far more work than it's worth...
The 6U5/6E5 tube was one of the most commonly used magic eye tubes, it was most often used as a signal strength indicator in 1940s and 1950s consumer radios. Indicator tubes with round displays were somtimes referred to as "gooney eyes". The 6U5/6E5 is mounted in an antique 6 pin...
so that I could avoid using a “standby” switch. This necessitated adding an additional stage of LC filtering to the supply as well as additional filtering for the driver stage. (This is the 2.58K / 47µf pair in the schematic above.) Here is the resultant power supply schematic. ...
