I am writing to thank you guys for documenting these improvements. I stumbled on this article and then this forum yesterday. I am in the middle of breathing life back in to a TS-530, two TS-830S's and a TS-830M (as shown on my qrz page). The photographs say a thousand words and help me confidently to look where the action is. Although this article was last updated a couple of years ago, those like myself still find snippets of well documented suggestions like this very valuable. Thanks. Greg G1CPU
