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