So I thought I would share my latest restoration piece with everyone, normally I just stick to vintage solid state amps from the 70's but a retired electrical engineer gave me the opportunity to acquire this unique piece of history and I couldn't pass it up! It is crazy that this oscilloscope is almost the same age as him! This sort of engineering and build quality is like a time capsule, never to be repeated, the high water mark for Tektronix! Weighing in at 33kg, consuming 500w of power at idle, silver soldering and containing 40 vacuum tubes, this oscilloscope is something to behold. First job was to replace the power connector, it was US based and annoying. I removed the old connector and cut it up to form a mount to fit a Delta IEC / EMI connector. This was press fit into the holder and epoxy potted.
