Posted on by hoppesbrain

Hi everyone, I’m really proud of this new power supply for the GFA-555! It’s been months in the works.

Hoppe’s Brain BFA-555 Smart Soft-Start

This is a whole new take on the soft-start power supply for the GFA-555 MKI and MKII. This version features:

  • An intelligent soft-start circuit that monitors a number of electrical conditions before starting the amp.
  • Easier to install than the old version
  • Remote trigger power
  • Better heatsinking of the bridge rectifiers
  • Additional bypass capacitor options
  • For the GFA-555 MKII, an option to replace back-panel fuse holders with on-board fuse holders, eliminating many inches of 16ga wire.
