Late-50's Gibson GA-6 Amplifier ....with some Very Unusual Problems

This video features a late-1950's (pre "Lancer") Gibson GA-6 amp that was brought to me for repair. The symptoms: wildly excessive volume, intermittent hum, and rather shrill tone. I must admit that I've never before encountered an amp that could literally blow the cone out of its speaker at a volume setting of 3, so this was an unusual challenge. Also, along the way, several pitfalls, cautionary tales, and examples of idiocy were discovered that should prove quite amusing. It all ended well, however. I hope you enjoy watching how it was done.
