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. ![]() ![]() ![]() Last edited by Musik007; 26th May 2010 at 04:16 PM. Reason: adding new photos |

These are old 6H8C twin triodes which were made in Soviet Union. The specification of 6H8C is same as 6SN7.

The power transformer is 200VA EI 96 x 60 x 0.35mm steel core. The output voltage is 290V-0-290V/250mA.
We can order the power transformers in other voltages like 100V, 110V and 230V, etc. |

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