DVE DSP-508A power supply unit schematic

Postby mpattonm » Tue Apr 25, 2017 9:23 am

Hello,

does anyone know if this schematic is available online somewhere? Alternatively I would appreciate some hints as I have a unit for repair, which is miserably failing on input line (blows 1A fuse instantly). No visually burned component or PCB issue.

Thanks!

Hmm so afterall, it was not that hard. I have suspected that big ceramic x2 capacitor in input L-C_L filter, but it turned out rectifier bridge was blown. Cleaning, recap and looks like I am gonna have spare STE PSU :)

Try searching http://dev-docs.atariforge.org/ for "PSU". I uploaded some a long time ago, not sure which ones as I am on lunch break.

exxos' LaST upgrade helped me quite well fixing my STEs psu. He has listed more than just the DVE DSP-508A psu and even shows how to improve them for useage in old Atari hardware.
