This is the first in a series showing the restoration and modification of an EICO ST-70 Vacuum Tube Integrated Amplifier that I just recently acquired. I've always wanted to restore one of these because I remember my cousin having one that he built from a kit in the 1960's. This video jumps around a bit, as I'm still deciding how to tackle this project. The long journey begins!
