Hi all
I found some time to repair the 2445B. There was some damage on A5 board from the SMD capacitors. I replaced most electrolytics on PSU boards except the big blue Spragues and of course the RIFAs.
On first power-up after repairs it would display TEST 05 FAIL 44, but not anymore. It appears to trigger correctly. It only has 300hrs on its clock, the Dallas RAM is from 1992.
Next I will have a look at the 2465B. I think I'll replace the same capacitors in the PSU (A5 board doesn't have surface mounted components, fortunately). Then I'll check the above mentioned components mentioned by Ozan. This scope has many more hours on it, like 5000. I only get to keep one, it will be a tough decision.
It has a Keeper II LTC-7P 750mAh, date code 0489 instead of a Dallas chip. I assume it can't be replaced by a Ramtron part? I'm thinking of ordering here:
