I am a Japan-resident New Zealander and audio hobbyist (Accuphase CD player, Leben amplifier, Blue Circle amplifier,
JM Reynaud speakers, other) . A while back some forum participants asked what happened to Almarro, a Japanese maker of SET amplifiers and for a short time, speakers. They had wanted a schematic of a product and noticed that Almarro's website was down. Having visited Almarro a few times, I can answer this question. First, Almarro was never a company but a brand name of the Network Supply company in Nagano Prefecture. (1938 Kanaenakadaira, Iida-shi, Nagano Pref., Japan 395-0801). It never launched a website in Japanese and sold only in markets outside Japan. Very few people in Japan would know of this brand's existence. The three (A31B, A205A, & A205AMk II) SET amplifiers it made, however, received critical acclaim, especially the A31B which used Soviet 6C33C output tubes and which a positive feedback reviewer declared a "sonic miracle". 6moons also sang its praises. (I auditioned it in my home and it would have been the last amplifier I ever owned except that it ran volcano hot and would have cost a fortune in electricity bills. But it was other-worldly good.) Some two-three years ago Network Supply appears to have decided to focus its core business and wind down its hobbyist-like audio equipment venture. I suggest sending a request for a schematic to the company at the address above. I expect that the request would be met.
