hello Max,
that`s very nice,
but the 564 have a pair of dual differential amplifiers in the slots, there is no time base.

Most of these have been restored and working, but not these 2 scopes.  Note the red tags.

Yep, my American Heath V-7A VTVM has a British meter courtesy of a fellow blogger in the UK. The original American meter had damaged bearings.

Many moons ago, I worked in a company whihc had a few of the Tek instruments you are showing here. I know they are VERY HEAVY.

And from the photo, it looks like your lab is located in the attic.

I hope you did not break your back carrying all that stuff up the stairs.  ;D

Mostly in good working condition except for the Dumont:

RCA WV98C VoltOhmyst VTVM
Dumont / Fairchild 401 scope
Fluke 412B High voltage supply
HP 400FL ac voltmeter
HP 401 oscillator (tube or FET??)


But alas, none have been used in years  :'(
