Tony, if someone sends you a batch of Technics commercial style disks, then shame on them! Most of us have paid a lot of money over the years for our style disks, and Technics has put out quite a few of them for us, but if we all gave them out to whoever asked for them, then who would develop any new ones? I paid $35 and up for my disks and I had a goodly amount of them. I would suggest you do the same, then do as most do and look out on the internet for styles from other brands to convert and recycle. Even then, you will find quite a few styles that were originally Technics and converted to the other brands. Just convert them back. You can also go to sites that offer kn6k styles for downloading, free of charge.
