این برند آلمانی آمپلی فایر 10 وات ترانزیستوری ساخته که مدار ساده ای داره، کلا 10 وات خروجی Class A داره و مثل نلسون طراح پروژه First watt این اعتقاد رو داره که راه رسیدن به صدای خوب کاهش توان خروجی است.

This was so very first watt, here by way of a 3-stage 4-transistor class A design pulling an honest 150 watts from the wall to make all of 10 watts into 8 ohms (8 into 4Ω).

Over the past 20 years I’ve heard many components of course. To me the best-sounding amplifiers were almost invariably the small ones that made just a few watts. They had simple circuits cleverly finessed to overcome the typical problems of linear amplifiers. Our CA10 is based on the so-called 4-transistor topology. All transistors are operated in pure class A. The amp uses current feedback into a single-ended input stage.

The arc from studio and broadcasting work to repairing then modifying and finally designing electronics has many successful precedents (I’m thinking Roger Modjeski and Dan Wright for just two). It seems to be a far more practical education than any formal university degree could provide. The craftsmanship of Ralph’s work also looked impeccable while the pricing was competitive with other low-power transistor precedents by FirstWatt and Linnenberg Audio for just two again. On paper, this had all the makings of a SET outing where ‘t’ stands for transistor and ‘SE’ are my initials.

این آمپلی فایر جزو لیست پیشنهادی من نیست اما بنظرم رسید برای تحقیق بیشتر معرفی اش کنم. فقط این آمپلی فایر های کم توان بلندگوی بالای 94 دی بی لازم دارند با امپدانس نزدیک به 8 اهم.

میتونید بیشتر در موردش تحقیق کنید، نلسون انگار پیشرو شده در طراحی آمپلی فایرهای کم توان ترانزیستوری.
