I have a few Tek parts laying around, free to anyone that wants them. I will need to get reimbursed for shipping unless you stop by our shop in New Berlin, WI (Milwaukee). I have the following:
7L12 pull button on bottom to release the plugin from the mainframe.
670-3114-00 CIrcuit board and switch for a 7L13, this has a typical Tek barrel type rotary switch with a thin rod through the middle of the shaft which operates a pot on the back. The shaft is broken off at the front but he rest of it looks ok, probably suitable for parts.
0510-01/152-17. This is a RF module for a spectrum analyzer, don't remember which one but it was probably a 7L12, 7L13 or 7L18. It is non functional. Maybe repairable?
