It has been a while since I had my TR3, but I was fairly sure that the band switches were silver plated. The black "soot" is silver tarnish (still a great conductor). I think the copper color would indicated you destroyed/removed the thin silver plating.
Is anyone on the list aware of the TR3 and know if it has silver plating or just copper on the band switches? 73, Ron WD8SBB --- On Mon, 11/16/09, Brett Forehand <[email protected]> wrote: > From: Brett Forehand <[email protected]> > Subject: Re: [Drakelist] Refurbishing a 'new to me' TR-3 > To: [email protected] > Date: Monday, November 16, 2009, 4:06 PM > Hi > Bob!
