Mr. Bonner. I MAY have been using Radio Shack parts for probably more years
than you have been around (beginning with the original Radio Shack Store in
the early 50's located on Tremont Street in Boston) and have been very happy
they are there although they do not carry as much as they used to in the
parts catagory. I have been pleased to have a store close by that I can run
down to to pick up a part when I need it. Thank you very much. You
sounded like for some reason you were almost ashamed to pick up a part at a
Radio Shack store. Just be thankful you found what you were looking for
when you went there! And that they are around when we need something they
still sell in their electronic parts inventory. Van, K7VS
