I have owned a TS-850S since 1992. From 1999 to 2022 the rig was never used. Last year I started fixing all the known bugs and adding the mods I was interested in. The two caps in the audio part on the IF-Unit and the other two caps in the power supply are still missing. However, I will soon replace these four caps as a preventive measure, although they still look good. But we all know from the CAR-Unit that caps can also leak invisibly under their housing. Thanks for the reminder, otherwise I almost forgot to replace the caps. Vy 73, Dieter, DF5EN
