This is the '70 I got from click2media last fall. As with any vintage amp it was a total gut and rebuild. Parts reused were the transformers, chassis, fuse holder, bias pots, and speaker strips. The bias pots are date coded 60-07, so I imagine this puts it sold in late 1960 or early 1961.
Before pics:
Before and after polishing the chassis, took exactly one hour. It ain't perfect but presentable.
Driver circuit plate mostly built ready to install. Circuit is the HF-89 / Ike driver.
