I've got a PT380 and need to do an annual capacitor check. Anyone here have a good explanation as to how I access them without removing the boards? Any other pointers? Not looking forward to this! LOL

Did you check with the company for maintenance instructions?

Specs and procedure are in the manual, just wondering if anyone had any additional tips. It might not be as hard as it looks to get at them but it looked tight when I installed it. Manual doesn't say anything about discharge, but it calls them line filter caps so I'm thinking that means they are operating as high frequency shunts (so no discharge necessary).
You only do the 4 staring at you when you open the cover. When I've done mine I just wait 30min or so after turning power off to it, unscrew a wire from a terminal and stick the DMM on it. I haven't had an issue with access, not the easiest thing to do but certainly not difficult. Mine have bleeder resistors across them.

What capacitor parameter are they having you test?
