As far as the replacement caps, I've decided to use Polymer Aluminums. These have the advantage of lower ESR and higher ripple current (not really necessary for the 8060), but best of all, due to the organic polymer, they will not spew electrolyte. These 8060s should last for another 30 years. I only had one value I could not fit physically in the position. So I went with the Nichicon UTT for the 22uF/16V part. All the rest are Nichicon RS, RNS or RNU types.

All these parts are in stock at Mouser.

Do you have a handy list of the part numbers, please?

'Do you have a handy list of the part numbers please' is considered more courteous.

They're completely different things.

The choice of glue seems important. Loctite professional is the way to go according to several web sites.

I tried bicarb with the cheapest available liquid super glue for experiment (not on any actual plastic). It does become very solid. I can't say how it compares to other glue, though.

Continuing to use sharp metal self tapping screws into flimsy thin plastic posts from the 1980s till recently, on EXPENSIVE professional and industrial Cat rated meters,
severely compromising their containment strength in an unfortunate  -meter blowout-  scenario, as shown in the scare tactic 'marketing' videos   :scared:     is  D U H City...    :palm: :palm:

I have encountered those problem occasionally, but never on a meter that was owned by me from first hand. Why? My screw-in procedure starts with a little search rotation to the left, then you feel the start of the pseodothread cut by the screw before.

Anybody with more then two brain cells does that.

The problem is the sheer amount of torque needed when you're near the end of travel. Thread or no thread.

(also the torque of the first insertion. The posts in these meters aren't huge)

I wonder if Dr.T has any insight on this design decision...
