--- Quote from: ZGoode on August 31, 2024, 07:33:03 pm ---I might replace the power supply eventually, but it appears my unit is one of the final ones produced of the latest revision, so it actually looks fine.  I pulled out all the electrolytics on the power supply and they all tested well within tolerance for the moment.

Yeah no need to replace if it a set of new caps will do the job. I just wanted to show that it can be easier and cheaper to replace the PSU if the original one is badly damaged.
The replacement PSU is a Meanwell RPT-60B.

DeepLink:
If you want to run your counter 24/7, as you now have an internal OCXO, do get high quality 105°C long life electrolytic capacitors with low ESR
