Gerald Weber is back with his third video on the inner workings of tube amps. It should be noted at the outset that this video is geared to advanced technicians (Weber has other videos for beginners).
In this one, he covers advanced servicing and overhauling techniques; different types of silverface amps and how to convert them to blackface; idiosyncrasies of Valco-manufactured amps (Supro, National, Gretsch, among others); how to check output transformers in Marshall and Fender amps; how to analyze any “mystery” transformer using only a multimeter; advanced tips on overhauling the Ampeg SVT amplifier.
Weber takes his usual loquacious approach to diagnosing, inspecting, troubleshooting, servicing, repairing and even playing the amp, which makes it both easy to understand and well-paced. Certainly, his years of experience come through clearly and the format is in many ways better than a book. Useful and excellent.
