Just what I wanted

I got this mint looking TR 457 and I wanted to restore it. I discovered the power supply caps were bad so I decided to recap the whole radio. Klondike Mike has put together a good kit. I have done three other radios and KM kit is the best in my opinion.

Very satisfied!

... the capacitor kit was exactly what I ordered, price was fair, quality seems good, not like the Chinese counterparts, and shipping was fast.
Thank you .

Electrolytic capacitor kit for Realistic TRC-457/458, Cobra 138/139XLR

 

This kit is built for radios using the PC-196BD, PC-196AA and PC-346AA main boards. All of the radial capacitors in this kit are rated at 25v or better, which meets or exceeds those specified by the manufacturer. 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. A link to down-loadable instructions will be provided. This kit includes 51 components in total.

The capacitors will be packed in a thick walled plastic envelope that is nicely labelled. The plastic envelope has a hang hole so that it can be placed on your workbench peg board. This plastic envelope will then be placed in a cardboard re-enforced bubble mailer to make sure it arrives safely at your location. I will also include a label that can be placed inside the radio identifying that new electrolytics have been installed. 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.

Due to inaccuracies in manufacturers documentation and undocumented revisions by same, this kit may not be a perfect match for your radio. It will be close but there is the potential that your radio may have one of these undocumented inaccuracies of which I am not responsible for supplying any after purchase additions or replacements.


** The buyer is fully accountable for proper installation of these parts. Any damage to a radio due to improper installation is the responsibility of the buyer. **

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."
