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
(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
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.
