Is there a site with the tube complement of ancient Tektronix 'scopes, the ones from the 50s and 60s? I thinking of the 514 and the 516 in particular. There may be other Teks with those model numbers, but these are getting way back there. The 516 has the traditional blue, rounded on top, side panels that swing open, but the 514 is really a dinosaur. The innards slide forward from the case for maintenance. The case is squared off on all edges. I'm not inclined to download a schematic, as all I want to know is which tubes are common to both.
Thanks.
