Adjust the oscillator/mixer trimmer cap on the tuning cap, (A4) for loudest noise. If the peak occurs at one end of the adjustment range or the other, return the trimmer to its center position and adjust the oscillator/mixer coil for maximum noise first, and then repeat the trimmer cap tweak. Only do this coil adjustment if absolutely necessary.

Because of this ability to change the resonant frequency, the variable circuit function. A group of coils and capacitors can, for instance, comprise a network.
This really doesn''t sound like a good idea. A capacitor in parallel with the diodes and their current limiting resistor might work in some configurations, but not all, and could introduce other problems. There are a lot of different configurations that you could be dealing with, and the best outcome of adding a capacitor would be that the LEDs would always run at full brightness.

VARIABLE CAPACITOR BASICS A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore they are sometimes called tuning capacitors), or as a variable reactance, e.g. for impedance matching
For higher adjustment resolutions, multi-turn trimpots are used. The amount of turns varies between roughly 5-25, but 5, 12 or 25 turns are quite common. They are often constructed using a worm-gear (rotary track) or lead screw (linear track) mechanism to achieve the high resolution.
Device construction & Distinguishing traits. Trimmer and variable capacitors are devices that provide a capacitance which is variable within some range, the difference between the two terms being mostly one of design intent; a “trimmer” capacitor is usually intended to be adjusted only a handful of times over its service life, while a “variable” capacitor anticipates
Removing the voltage rearranges the conductive particles, reducing capacitance. In practical applications, you can combine multiple variable capacitors on a single shaft to create coaxial variable capacitors (commonly known as dual, triple, or even multi-gang capacitors).
Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore they are sometimes called tuning capacitors), or as a variable reactance, e.g. for impedance matching in antenna tuners.
Adjustable capacitance makes these capacitors essential for fine-tuning electronic circuits. In electronic applications like radios and oscillators, their ability to adjust capacitance by changing surface area, plate spacing, or dielectric material allows for precise control.
Because of this ability to change the resonant frequency, the variable capacitor is called a "tuning capacitor" or a "resonating capacitor." The electrical equivalent of the parts in Fig. 1 is offered in Fig. 2. The arrow through the capacitor indicates it is ad- justable.
Differential variable capacitors also have two independent stators, but unlike in the butterfly capacitor where capacities on both sides increase equally as the rotor is turned, in a differential variable capacitor one section's capacity will increase while the other section's decreases, keeping the sum of the two stator capacitances constant.
In electronic applications like radios and oscillators, their ability to adjust capacitance by changing surface area, plate spacing, or dielectric material allows for precise control. Anyone interested in electronics must understand these components' operation and maintenance, whether they are electronically or mechanically adjusted.
