That is a nice collection of scopes.
I have pressed my 7603 into service. It still needs one channel of one Y amp sorted out as it has an offset on it that drives the gain down beyond the range of the pot.
There is no need to pull it down from my test gear rack as the Y amp can be run from a dual channel bench power supply with care allowing me to find the leaky capacitor.
I suspect it is in the HF correction area and would be best searched for using a static bench environment.
It was free but with three faulty plug ins and a fault in the frame so it will have been cobbled together from a pile of duff bits.
I am still on the look out for a couple of knobs for cosmetic reasons and a rear heat sink cover with screws. It also came with no bottom cover but that is less important to me as it is on a high enough shelf that I will never use the tilt stand.
