Voltage driven from input to output, the LV-105 is centered around two 6CG7A twin-triode vacuum tubes.in the driver stage. Power output is delivered by high-current MOS-FET transistors. Duo-ßeta circuitry allows for a 14 octaves linearity : from DC to 200kHz. Along select FETs in the first stages, the STAR circuit topology groups ground lines, power and signal patterns by the amount of current instead of location - the electrons thus flow more naturally and efficiently. Two power transformers are used : one high-flux core feeds the audio circuitry while the other deals with the video circuitry, the 6CG7A tubes. Primary and secondary windings on both trafos are properly phased in.
The tubes pre-heating system
operates plates at less than 50% of their voltage with the heater itself
set at 80% of its voltage.
The overall build quality is
however somewhat "industrial" and not too well matched to the ingenious
hybrid circuit... Depending on the market, the LUXMAN logo was preceded by the ALPINE logo. Argh.
