An integrated amp based on the Dynaco Pat-4 preamp and the ST-80 (Stereo 80)power amplifier. Fully functional and ready for refurb and mods. A great starting point in that it's complete and working with surprisingly little hum though I'm sure the electrolytics are tired.
I had planned to do a variety of mods and refurb the unit for my daughter. She took a tube route so this baby is sitting around collecting dust. It needs to good home and an owner to make it sing. If you're unfamiliar there are loads up upgrades and mods to pursue.
Front panel is pretty clean except for a small mark in the center. With a bead blast and paint job, the will be better than new. Controls and connectors need some cleaning as expected.
