How do I set up the amplifier after receiving it?
-
Unpack the device and place it on a flat surface
-
Install the vacuum tubes in their sockets
- Small tubes at the front, large tubes in the rear sockets.
- The sockets only allow installation in a certain direction. Please make sure that the direction of the tubes matches that of the socket and make sure that the connectors of the tubes are not damaged when they are inserted into the sockets.
- Please proceed carefully and ideally wear gloves during installation to avoid dirt or oil/fat swab on the tubes.
-
Connect the head-plugs onto the large rear tubes
- Please make sure that the connectors are placed in the middle of the contact, snap them into place correctly. Ensure they are properly stuck after connection and cannot be removed easily.
