Electrolytic radial capacitor kit for Realistic TRC-457/458, Cobra 138/139XLR (PC-196BD, PC-196AA and PC-346AA.)

All of the capacitors in this kit are rated at 25v or better. Install any capacitor with the stock 10v value would be a serious mistake. Uniden did this as a cost cutting measure which has proven to be the cause of many failures over the years. A higher rated component means that it will last longer in your unit. Some vendors are even including 100v or even 200v capacitors in their kit! See note at bottom of this listing as to why this may be a detriment for a radio that can be powered by 12v. These capacitors are from Tier 1 manufacturers with no Chinese counterfeits.

The board number that this kit has been built upon is PC-196BD. Other similar boards are noted in the title. A link to down-loadable instructions will be provided. This kit includes 51 components in total.
Restore your radio back to its original glory with the proper kit!

The following brands used the board PC-196XX, w/µPD858 PLL, in their top of the line models. All of the main boards are identical. Certain brands incorporated added features such as the LED Dimmer control found on the Cobra 138XLR.

Power Tip 50: Avoid these common aluminum electrolytic capacitor pitfalls

"This life-temperature dependence actually impacts how you should derate the voltage on the capacitor. Your first thought might be to increase the capacitor’s voltage rating to minimize the possibility of a dielectric failure. However, doing so can lead to a capacitor with a higher equivalent series resistance (ESR). Because the capacitor typically has a high ripple current stress, this higher resistance leads to extra internal power loss and increased capacitor temperature. The failure rate increases with the increased temperature. In practice, aluminum electrolytic capacitors typically are used at about 80% of their rated voltage."
