The Soviet quartz resonators RK-58 1000kHz gold plated were electronic components that were commonly used in Soviet-era electronic devices, such as radios, televisions, and other consumer electronics. A quartz resonator is a device that is used to generate a precise frequency or time base in electronic circuits.

The RK-58 quartz resonators had a frequency of 1000kHz (1MHz) and were gold-plated to provide a stable and reliable frequency output. The gold plating helped to protect the quartz crystal from oxidation and other environmental factors that could affect its performance.

The RK-58 quartz resonators were known for their high accuracy and stability, which made them a popular choice for use in electronic circuits that required precise frequency control. The quartz crystal in the resonator would vibrate at a specific frequency when an electrical charge was applied, and this vibration would then be used to generate a precise clock signal or other timing reference.

While the RK-58 quartz resonators are no longer in production, they remain an interesting piece of Soviet-era technology and a unique part of electronic engineering history. Today, vintage RK-58 quartz resonators can be found in old electronic devices and may be of interest to collectors of vintage electronics or anyone interested in the history of electronic technology.
