| Hydron:
No schematics, just looked for the Y-caps across isolation barriers (they are pretty obvious). As you've found out it's a massive pain to work on though! If you're lucky you might be able to just do a snip-snip job on the caps without pulling it entirely to bits - it's been a while and I can't recall how badly they are buried though sorry. |
| David Aurora:
OK, finally made the effort to pull it apart enough to get those caps out. Much better, but still not great. I don't think I could be bothered trying to improve this thing any further given the lack of schematics/pain it is to disassemble, time to build something else for the task at hand I reckon. |

I measured the voltage between GND and the minus with the main switched turned on to 69VAC A 10uF 400V between GND and minus pole reduces the voltage from 69VAC down to 69mVAC. |
| Hydron:
Deleting the existing Y-caps which were across the isolation barrier, and adding 100nF of earth - negative capacitor reduced mine to something like 400mVpk-pk. Could have put something larger in there to reduce it further, but ~100nF seems fairly standard and what's left seems low enough to ignore. |
