New EL34/6CA7/KT66 integrated amplifier

Musik007 · 03:16 PM

Our second new tube amplifier in May is available now. The circuit is 6SN7 SRPP drive EL34 class A single end. It's a simple EL34 single end circuit with pure class A sound. The output power is 7W. 6CA7 and KT66 are also suitable for this amplifier.

Dimension of the amp: 365W x 320D(inclu. binding posts and knobs) x 200H mm.
Net Weight: 11.8 KG

Can directly replace KT66 onto the amplifier. It is very easy to listen and experience different sound on the power tubes.

One pair audio input and no selector used ensures direct signal path. The RCA sockets are CMC long style.
