This is a very timely thread for me. I was just examining my R-7 to determine how to extract the DR-7 board. A quick rummage through my junk box turned up several slot covers, and they do indeed look as if they're made for the task. Thanks for the ourstanding idea!
The tuning on my R-7 is slightly stiff when the unit is at room temperature, but after warming up for a half hour or so the knob rotates much more freely. I'd guess that the lubricants used in the VFO have become somewhat dry over the years, and that after being subjected to a bit of heat they thin out. I'd like to carefully remove the old lubricant and sparingly lube the VFO where necessary. What' s the best way to go about doing this? 73, Rick K0VJ On Fri, Jan 8, 2010 at 08:12, <[email protected]> wrote: Message: 5 > Date: Thu, 07 Jan 2010 21:30:27 -0600 > From: "Jim Shorney" <[email protected]> > Subject: Re: [Drakelist] tr-7 readout replacement > To: "Drakelist" <[email protected]> > Message-ID: <[email protected]> > Content-Type: text/plain; charset="iso-8859-1" > > > This is the page that I used to make my copy of the Drake board puller.
