1. Re: [Amps] What are the drawbacks of using a tube running, relatively low voltage and high current? (score: 1): Author: Manfred Mornhinweg <manfred@ludens.cl>; Date: Thu, 07 Jan 2010 16:00:25 +0000; Roger, I would say that using a lower plate voltage affects these components POSITIVELY! Since the tube's capacitance stays the same, the lower load impedance resulting from the lower voltage and hig; /archives//html/Amps/2010-01/msg00044.html (9,794 bytes)
