David Berning ZOTL Amplifier

ZOTL atau Zero hysteresis Output Transformer-Less adalah penemuan David Berning yang sampai saat ini dapat dikatakan sebagai pelopor pembaruan tehnologi tabung sekaligus sebagai salah satu desainer amplifier yang terkenal di dunia.

Sering kita katakan bahwa suara tabung itu hangat, bulat dan nyaman di telinga….tidak mudah lelah dengar musik dengan peralatan tabung.
Maka ZOTL Amplifier malah memiliki kelebihan berupa keindahan dan keluwesan yang tidak dimiliki amplifier lain dengan trafo.

Selain itu umur tabung akan mencapai minimal 10 tahun jika dipakai selama 5 jam tiap hari.

Kami anjurkan untuk mencoba serta membandingkan produk ZOTL Paten milik David Berning ini sekarang di tempat/ruang anda.
