The purpose of this group is to explore and build your own old-school style VINTAGE tube amplifiers for vintage speakers and headsets or radios. We will design and build our own and exchange ideas and information about circuitry, perils and pitfalls as well as the pleasure of the uniquely warm sounds created with vacuum tubes. Also want to discuss the best avenues for obtaining parts. Must have some knowledge of vintage electronics or willing to learn. Must have respect for the potential unpredictability of working with electrical devices. Ideally would like a good mix of experienced electrical engineers and novices willing to learn.
