I pulled an L5 from a spare AF-AVR PCB that went to a TS-830S. It measures 2.87mH on my tester
and its got this number stamped on the metal band: L15-0016-05. Searching online for that term reveals its used in
some other later Kenwood riggs. It does not look burnt or overloaded, so installed it into my 530S's PCB. Have not powered up yet
but I am guessing it will be fine.

The choke used in the '830 line (and a number of other Kenwood rigs) in P/N L15-0016-05. No data appears about this part online, though it's available to order from PacParts. I dug into my junk box and found a few chokes of the same form factor; these had been salvaged from CB sets over the years. Using the LCR bridge with a 120Hz test signal, I inspected the lot. Of them, I selected an 8mHy part; it had a measured Q of 3.6. The windings look to be good for 2-3A, which jives with an SSB CB's power requirements.
