Default SB-101 available for restoration


I have a Heathkit SB-101 with matching speaker/power supply and one or
two other associated odds and ends that I'd like to get into the hands
of someone interested in restoring it. It actually seems to be in
decent shape. The major exception is that something is mechanically
limiting the VFO to about 200kHz rotation. Includes manual. I would
prefer to find a new or needy ham with enough technical background
that a bit of work on electronics isn't daunting. For such a person
in the Seattle area, the price will most certainly be right: come get
it. If I have to ship it, you'll pay shipping and something to
compensate me for packing it up.

Tom, I have a couple of those VFO's. I'd wager a buck to a doughnut that the
problem is the geneva wheel. There's a 5 turn one on the front of the shaft
and Heath lubricated it with something that turned to gum which welds
several of the wheels together. A drop of WD-40 or acetone or the like frees
it up so it acts like a Geneva wheel again. Clean it off and lube with some
good Moly and it'll never happen again.
