不要选择失速电流消耗超过解码器额定值
以下程序可用于确定机车的失速电流：1.将机车放置在一段轨道上，该轨道由常规直流电源组供电，N、HO、s和O刻度设置为12伏，G刻度设置为16伏。2.如图1所示，将直流电流表与其中一条轨道馈线串联连接。如果您的电源组有内置仪表，则可将其用于此目的。3.握住机车以防止其脱离时，将电源组调至全开状态。4.通过将机车牢牢推入轨道或抓住飞轮或传动轴来停止电机转动。5.为了确保最准确的电流测量，请确保在此测试期间，电源组电压保持在12伏（G刻度为16伏）。6.测量电机失速时机车的电流。这是失速电流，必须小于解码器的额定容量
扬声器磁铁
正确的扬声器外壳的使用再怎么强调也不为过，不使用扬声器外壳几乎总是导致音质差的原因。幸运的是，大多数蒸汽机都有一个外壳，只要稍加努力，外壳本身就变成了一个很棒的扬声器外壳。扬声器可以面朝上穿过煤仓，也可以面朝下穿过地板。无论哪种方式都能产生同样好的声音。您还需要尽可能使用最大的扬声器来获得最佳的低音响应。更大直径的扬声器可以在宽度上进行修剪，以便它们能够安装在柔嫩的外壳内。通过构建内部挡板，它们也可以以一定角度安装，尽管这会影响DSD模块的可用空间，但最大的投标除外。在小型投标中，扬声器应安装在煤仓区域的前方，那里有较高的墙壁覆盖扬声器磁铁。
Do not select stall current consumption exceeding decoder rating
The following procedures can be used to determine the stall current of the locomotive: 1. Place the locomotive on a track that is powered by a conventional DC power pack, with N, HO, s, and O scales set to 12 volts and G scales set to 16 volts. 2. As shown in Figure 1, connect the DC ammeter in series with one of the track feeders. If your power pack has built-in instrumentation, you can use it for this purpose. 3. When holding the locomotive to prevent it from separating, turn the power pack to the fully open state. 4. Stop the motor rotation by pushing the locomotive firmly into the track or grasping the flywheel or drive shaft. 5. To ensure the most accurate current measurement, please ensure that the power pack voltage is kept at 12V (G scale is 16V) during this test. 6. Measure the locomotive current when the motor stalls. This is the stall current, which must be less than the rated capacity of the decoder
Speaker magnet
The correct use of the speaker shell cannot be overemphasized. Without the speaker shell, the poor sound quality is almost always caused. Fortunately, most steam engines have a shell. With a little effort, the shell itself becomes a great speaker shell. The speaker can be face up through the coal bunker or face down through the floor. Either way can produce the same good sound. You also need to use the largest possible speaker for the best bass response. Loudspeakers with larger diameters can be trimmed in width so that they can be installed in soft enclosures. They can also be installed at an angle by building internal baffles, although this will affect the available space of DSD modules, except for the largest bids. In small tenders, loudspeakers should be installed in front of the bunker area, where a high wall covers the speaker magnet.
