With these speakers you will hear an unprecedented richness, refinement and elegance. The harmonic coherence of music remains beautifully intact. This is a Single-Ended Triode 2A3 amplifier, designed as it should be and supplied with the best transformers (TAMURA) available.








Sun Audio SV-2A3 (new chassis)

Sun Audio has developed a new chassis for their SV kits.
The new chassis looks exactly the same as the old version (so happy that they did not change that), but the humm balance potentiometers have been relocated. These are now located directly in front of the output tubes and can be set without the need to put the amplifier upside down.

All (brands of) output tubes are made a little different. When changing output tubes it is sometimes necessary to adjust the "humm balancing potentiometer" to achieve the lowest output humm.

Re-designing the chassis also offered the possibility to use new high quality input sockets and new loudspeaker terminals


It also offers the possiblility to upgrade the output transformers to the F-2007 output transformers.

To increase reliability and sound, expensive Yamamoto tubes sockets are now supplied for the output tubes.
