Gold mine of DI¥ audio tubes schematics from Japan

Decades ago I lived in Japan, but learning kanji signs difficult for Europeans.
Not impossible, but many, many years of intensive learning.

In the primary school the requirement about 2000 sign, at the highest level (for example in the literary university) more than 6000!

The hiragana is simplest, contains "only" 107 compound signs.

Valve amplifier kits


This link looks interesting, kits appear to be available.

This is a preferred option, rather than trying to locate all the parts and from so many different places, which would make the final price on postage/courier pricey.

Comparisons of valves used in those builds compared to Western builds?
