I bought some guys electronic stuff off ebay and this was amp was part of that.
in this you see some basic cleaning and me failing in installing a new backlight to the VU-meters.
This unit is the Hornyphon hifi sound project 6391. It was also known as the Philips SX6391 or the DUX 6391.
nothing too special but I am now using this as my primary PC amp.
A big thanks to radiomuseum.org for some basic info on this!
Also some pics for the ride:
Live long and Prosper!
