Výsledkem by měl být dostatečně výkonný 100÷200W dvoukanálový zesilovač špičkových vlastností. Diskuzi otvírám pro zjištění zájmu, nejenom o konstrukci, ale i o potřebné vstupy a výstupy. Zdroj předpokládám pulzní na samostatném plošném spoji, ve dvou variantách, jak z napětí 12V tak z napětí 230V. Kdo bude chtít použít klasický transformátor tak mu nic nebude bránit.

Schéma blíže k realitě. Ještě není kompletní, ale zase o kousek dál. Zatím mi vychází dát na regulaci citlivosti pro každý kanál potenciometr, následovat budou basy a výšky, jako poslední hlasitost. Možná bude hlasitost jako prostřední, to se ještě rozhodnu.
