Single-ended triode amps

摘要

'Hot, huge and heavy' is how Alternative Audio describes its latest import - the Se2se monoblock 'single-ended zero feedback' triode amplifier from NAT Audio in Serbia. Weighing in at 34kgs and measuring 300×260×610mm (whd), each of these monoblocks employs two 211 new old-stock triodes manufactured in the 1940s and configured to deliver a ratedrn70W in Class A.rnPartnering this behemoth is the NAT Audio Plasma R preamp, a dual mono design again featuring valve rectification, little or no overall feedback and high current 6N30P-DR tubes driving the low impedance output.
