10 Rack Mounting

The SM-500 requires two full rack spaces (3 1/2") and should be mounted at the bottom of the rack case. If mounted in any other rack space, additional support should be installed below the SM-500 to prevent continuous flexing of the amplifier's chassis which, over time, can damage the amplifier and void warranty coverage.

Please routinely check the mounting and chassis screws which can vibrate loose due to transportation and use. We recommend that at least once a month that the SM-500 be removed from the rack case and all outside screws be tightened and all connections in your rack case be checked to preserve the beauty and reliability of your equipment.

Tube Replacement

One 12AX7 dual triode vacuum tube (valve) is at the heart of your SM-500 pre-amplifier. Typically a 12AX7 tube will last several years, but heavy use and frequent transportation can reduce tube life span to less than a year.

When to replace the preamp tube: Sometimes, tubes become noisy or “microphonic” (sounds like glass chimes during certain notes) as they wear out, but other times, tubes will fail without warning. If your amplifier stops working and other possible causes have been eliminated (fuses, cords, etc.), have an authorized service center inspect your amplifier tube.
