Are you seeking in-depth information on the operation of valve amplifiers? Then this double layer DVD is what you want.


This high-quality DVD contains 165 minutes of masterclass and much more presented by Menno van der Veen. Topics discussed include valve load line graphs, current sources and current fold-back techniques. The negative effect of cathode electrolytics is covered as well as how to reduce supply voltage interference. With the help of state of the art measurement techniques Menno proves the (in)correctness of feedback and he shows you in detail the inner workings of the core of the output transformer.


The DVD includes:
• Valve Preamplifier presentation (75 mins.)
• Valve Power Amplifier presentation (90 mins.)
• Other publications by Menno van der Veen
• Lecture Notes (27 pages)
• Datasheets
