    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.

    These beast warms my heart, probably with the glow of high voltage discharge in trace gas.

    Big day!

    Visited my favourite bolt shop and managed to source new fasteners for this unit, many of them have barely any top left from so many years of use, others just look horrible. Seems 6/32 and 8/32 was popular in the 1960's :lol:

    Also sourced new BNC connectors to ditch some of the old ones, a couple had to be cleaned as they are dual isolated. Also removed the valves for cleaning, gorgeous :leet:

    What a beast. Those spider web circuits kinda make me shudder though.

    Seen a similar unit (possibly even the same model) up at the Ch7 studio here and it is a very imposing unit. I’d guess some 16” high.
    I know a few guys who go up there regularly, should get one of them to get a pic.
    Wonderful restoration.
