I have problem with the tune cap arcing in the SB-220 and caused some damage to the components.
Recently I purchased one 5-250 pF vacuum variable from ebay and installed it for a trial. It works very good from 15M to 80M, but look like it is not working well on 10M. This problem need to be sort out when have free time.
