Many of my audio designs start out as a “request for comments” type thread on DIY Audio. In many cases, I get valuable inputs from other audio designers that I incorporate in my designs. If nothing else, the process serves as a peer review. Below is a list of some of my DIY Audio threads.

Power amplifiers, vacuum tube based:

  1. 6LU8 Spud – Request for comments
  2. RFC: 300B driven by anode follower (6J5/6SN7)
  3. DC coupled 300B idea – request for comments
  4. DeathTrap400™ : : A Pretty Damn Good 300B Amp

Power supply design for tube amplifiers:

  1. High Voltage Regulators (Maida or zener)
  2. 300B SwitchMode filament supply
  3. Universal Filament Regulator
