Got what I bargained for!!! Just wish tatalums came with it as well!!! That would complete the kit!!!! Very happy!!!! Thanks for putting together such an easy kit!!!!
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.
... 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 .
The board number that this kit has been built upon is PC-196BD. Other similar boards are noted in the title. All of the capacitors in this kit are rated at 25v or better. 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. 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.

Courier Spartan PLL

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."
