Notlar:
Trafo simetrik 24 veya simetrik 25 volt olabilir.
Şok diyotlar harmoniğin sert olmasını sağlar, 1N4148 ile değiştirilirlerse daha yumuşak bir harmoniğe sahip olunur.
Hoparlör seçimi ses kalitesi için en önemli unsurlardan ve ucuz yollu bir yöntem aranıyorsa mevcut kaliteli müzik setinin hoparlörü bu işi görebilir.
