A common problem. Using a Varitone or Varitone variation means switching capacitance. Depending on the switch’s design and its location in the circuit, this can result in a loud popping noise in a passive guitar wiring scheme if you switch capacitors. You can prevent this by turning down your guitar’s volume pot or putting your amp on standby, but what if you want to use the rotary switch mid-song? There’s an easy solution: Get some 10M resistors. (I like 1/4-watt metal-film resistors because of their small size, but you can use any resistor type or voltage you want, so long as it has the correct resistance.) Solder one between the rotary switch’s center input lug (labeled “Center lug connects to volume pot lug 3” in Joe’s diagram) and the lug the capacitor is connected to. You need to use a separate resistor for each capacitor, which means a total of three resistors if you follow Joe’s diagram.
The room thermostat senses room temperature and opens and closes a circuit as necessary. It is wired in series with the safety controls to control the flow of gas. Figure 10 shows our steam boiler with the thermostat and pressure control installed. There are many types of thermostats on the market today. All low-voltage thermostats have heat anticipators built in. This device allows the thermostat to allow for the heat generated by the wires in the thermostat. On a forced-air furnace, the flue damper, spill switch, and rollout switch will be the same as the steam boiler. The operating control is a combination fan and limit switch.
