ONE vintage transistor like sample shown Pict shows top and bottom of samples, but bid is per transistor, not all. Gold plated, hard to find. All were tested on a B K transistor tester. Pulled from old equipment that did not look to have had much use. May contain some residue from white heat sink compound. If you need a mica insulator ask with your order and we will include (also may have white compound on it but you can wipe and put new on)
