Yep. Repost pic from early in the week below.
Needs some love on the mechanics and also some recapping but it works ok as is.
Looks like yours is in a better shape than mine. I have here one sitting in my queue for some time.
When I opened it the first time and looked a bit closer I decided do put it together again and wait
for a second one. Explanation is in the pictures below. And if I could find this chap who did this
bodge, he has to answer some serious questions!

Backside, wired for 115V AC. And this nightmare of an AC mains connector will be replaced.

The PSU on the backside, the date code of the power transistors is 8616, seems there was a repair.
The instrument itself has been probably built in 1972, some caps have a date code of 7117.

Yep. Compared to the other solder joints it looks newer.

They are wired, of course!

Nice PCB with some more candidates for recapping.

Burnt PCB! Honestly, I don't understand why the PCB is burnt at this place.
I suspect a massive abuse of this poor little instrument.

Here is a more detailed view of it.

This! This is a really ugly bodge! Really, who is doing this?
Cutting the wire like that of a valuable and high precision resistor?

To bring down my blood pressure, a nice picture of these golden trimpots. Like them.

Mechanics of the switches. Very nice!

Now let's see what I can find in the bay ...
