Now this is the definition of a restoration. Rebuild of an old Gibson model BR-9 Tube amplifier. A very basic design. Utilizes an interstage transformer rather than an inverter tube. The amp had numerous problems, bad speaker, power supply caps, Open windings on the interstage and output transformer. Lots of time went into its restoration. If I did not have the rare parts in my hanger queen stash, the amp may have exceeded its value to fix. Have you ever looked on ebay and see what prices are on transformers! Its getting to the point where hobbyists cannot build and enjoy their creation. For this task, all turned out well and the amp is back with the owner. But now I am out of transformers for this application.
