Kendrick Amplifiers President Gerald Weber has overhauled and serviced
over 15,000 vacuum tube guitar amplifiers, designed dozens of new
model amplifiers and has produced thousands of boutique tube guitar
amplifiers. This DVD will transform your experience of tube guitar
amplifiers forever. Whether you are a beginner or a seasoned pro, you
will never see tube guitar amplifiers the same again. Topics covered
include: AC and DC voltage and current · resistance · capacitance ·
capacitive reactance and how this affects frequency response · voltage
division and how this principle is used over and over again in an amp ·
rectification (half-wave and full wave) · tone shaping (how to sculpt
tone from a tube circuit) · Ohm's law and its variations · vacuum tube
types and how they work (diode, triode, tetrode, pentode) · preamps
and the anatomy of a gain stage · Class A and Class AB differences ·
single-ended output stages and push-pull output stages (how they work
and how to recognize them) · five types of phase inverters (advantages
and disadvantages of each) · power supplies (economy, half-wave,
full-wave, full-wave bridge) · applications of these principles (anatomy
of the Tweed Deluxe, Tweed Bassman and Blackface Super Reverb) · and
much, much more!
