We did same for our pair of 2465. Fixed defective hybrids, bad waveform cal source, recapped everything, clean up and so on. Nice analog scopes!!

Best,

me too
I did a full capacitor recap
And in one of them defective hybrids replaced In the picture with the red arrow

2 were completely repaired and the third
Need to replace the A5 board
Basically the story started with a friend giving me the 2465 as a gift
To fix it, I bought a cheap 2445 for 70$
for the parts.
After I fixed the 2465
I couldn't not give 2445 a chance to come back to life
So I bought a cheap 2445 for 60$
I fixed the 2445 .
Then I wasn't able to it to give the third 2445 a chance
So I also completely repaired it, only it has the original defective hybrids from the first project
Needs replacement.
And an A5 board that needs replacement
In the future I will bring him back to life
Because I have no intention of purchasing another 2445
I am not able to take advantage this amazing equipment just as an organ donor

I bought most of my measuring equipment broken
and fix and calibrate them.
In Israel, old measuring equipment is very cheap
I will probably later buy the Agilent HP 83732B 10MHz to 20GHz Synthesized Signal Generator
that he can sell it to me for less than 1000 dollars

Nice job on the 1659 repair. Looks like that psu took some damage. My older 1658 , and newer 1689 both use a conventional transformer linear supply.

Bravo, great job. Wonderful machine,

My original 1659 GenRad is working OK but loud fan and the keypad decal gone.

Only quirks...

1/ Keypad decal often lost or damaged....Would love to get a keypad decal/overlay as you have made.

2/ The leaded component test connector needs a lead/4 wire/BNC adapter, they exist byt rare.

I would have added 4 floating BNCs to the front to replace the test connectors for use with ext 4 wire leads  or tweezers.
