I bought a used SB -610 from eBay. It has a blown fuse, a leaky capacitor, a nonfunctional selenium rectifier. It sounded like bacon frying when I powered it up. In this video, I use a recap kit from Hayseed Hamfest, who makes custom recap kits for many ham radio and other vintage electronics. I don't show the actual soldering, but I stop and show each step where the new capacitors are mounted. I diagnose the bad selenium rectifier. I do a fairly complete demo of the SB-610 using it to monitor the output of my Drake T-4XC transmitter, and I try out the tone generators on the SB-610.
