My friend purchased it and asked me to modify.
The below is my blog page(in Japanese) for the Audioromy 813.
Although its catalog says 22W output power but I measured
only 12W due to AC mains lower voltage of 100V in Japan
while the amp's specified voltage input voltage is 110V.
813 triode connected with 800V B voltage. I modified it
to reduce NFB value from 12dB to 6dB, resulting better
sonic was obtained. I can reccomed it if you accept lower
output power than the catalog.
