Line Fuse (A/C or Mains Fuse)

This fuse is provided to protect the internal electronics against power surges, etc. It also protects the unit against itself should one of the internal components fail. If this fuse should open, replace it with the same type of fuse and rating. Do not defeat the purpose of this feature by using a higher rated fuse as it can void your warranty.

Proper size of the AC fuse for all countries is 3AG. Proper rating of the fuse is as follows:

United States: 7 amp slo-blo

Japan: 8 amp slo-blo

Europe (230V-240V): 4 amp slo-blo

A/C Cord Receptacle

This receptacle accepts a standard A/C power cable (supplied with the 350x in the United States) used with almost all current musical, professional and household electronic devices. We recommend great care when packing up. If your unit is not in a rack case, put the cable in your instrument or accessory case or leave it attached and looped around one of the rack handles. If it does become misplaced, a replacement cable can be purchased at almost any music or computer store.

Note: The rating for this cable is 3 conductor, 10 amperes minimum. Look for this rating on the cable. Make sure the cable is plugged in all the way in both the amp and the wall socket.

Internal Feature: Vacuum Tube (Valve)

SWR installs a specially selected 12AX7A dual triode on the preamp circuitboard of every 350x. If this tube needs replacing, we recommend that you replace it with a similar high quality product. This tube will need replacing only if it becomes noisy or microphonic (which sounds like glass tinkling in the background of certain notes), or completely fails (causing no signal or signal at very low levels). The tube in your 350x should last one to three years, depending on usage.

RACK MOUNTING INSTRUCTIONS

To preserve the beauty and reliability of your amplifier, we recommend that you install your amplifier in a rack case. The 350x is completely ready to be rack mounted and needs no additional parts or accessories other than the rack screws and the case itself.

The 350x takes up two full rack spaces (3 1/2"). If the rack in which you mount your 350x requires that the rubber feet on the bottom of the chassis be removed, please remember to keep the screws handy in case you wish to reattach the rubber feet at a later date.

The 350x should be mounted as close to the bottom of the rack case as possible. If you must mount the 350x in an area of the rack other than the bottom space, a piece of wood or similar solid material should be installed between the bottom of the rack case and the bottom of the amplifier to prevent flexing of the amplifier’s chassis. Severe or constant flexing of the chassis can damage the amplifier and is not covered under the warranty.

Please do not forget about your amp after it has been installed in a rack case. Continuous transportation and vibration can cause screws to become loose, both on the 350x and with your rack case rails. We rec- ommend that at least once a month you remove the 350x from the case and tighten all outside screws and wipe off the outside of the chassis with a damp cloth. Then check all the connections in your rack case and reinstall the unit.
