Wow ! Congratulations on your giant lab !
I can only dream of such a big lab... I am in the process of building a similarly sized... garage/workshop, but sadly only a very small part of it will be able to be dedicated to TE stuff. That would be to store all my hollow-state Teks that are either for parts, or awaiting restoration.
I hope you have some kind of ventilation and/or heating system in that basement, to keep humidity from ruining all that nice TE ?
Not one but TWO 575 in just two weeks ?! That's insane ! Are they so easy to find, and so cheap in the US that you can afford a pair of them ?!
Here in Frogland they are super rare (maybe one every year or two) and ultra expensive.
I got mine 2 and a half years ago, and since then, the only other one that popped up is this one, a year ago maybe, priced at 1,500 Euros no less (add 10% to convert that to US dollars...), for what appears to be, literally, a " barn find", as is !

Anyway, so cool to see other people caring for these 575, two of them even, in a nice comfy lab to boot
Do any of your units feature the high-voltage / 400V mod, or are they both the standard 200V versions ?
I am planning on using the 575 to test vacuum tubes as well as semi-conductors (to help me restore the other Tek scopes
), so I would kill to have the 400V version, so I can properly test vacuum tubes up to their actual operating voltage. 200V is good enough to test the tubes for proper operation and "health" of course, but how nice would it be to be able to test them up to full operating voltage
