I recently heard that early P3's (first gen ?) used a different P3-to-K3 cable than the last generation of P3-to-K3s's did. Can anyone tell me anything about that? And is there a fix for connecting an eary P3 to a late K3s? Or was my leg being pulled? 🙂 Thanks, Doug W5JV Visit https://www.qrz.com/db/W5JV for some great vacuum tube finds.
