When reinstalling the power supply I noticed it is missing one of the power regulator insulators - It’s a cylinder-shaped piece of semi-transparent fairly stiff plastic through which the screw of the regulator goes. The insulator should be in the hole of the heat sink, preventing the regulator’s screw from short circuiting to the heat sink. The insulator measures as follows: OD 6.4mm (0.25in), ID 4.2 (0.165in), length 3.3mm (0.13in).</span></p><p style="margin:0px;font-stretch:normal;line-height:normal;min-height:22px"><span></span><br></p><p style="margin:0px;font-stretch:normal;line-height:normal"><span>Now when googling for this part it seems the modern equivalent is a type of a shoulder washer - these wouldn’t work, it needs to be ”shoulderless”.</span></p><p style="margin:0px;font-stretch:normal;line-height:normal;min-height:22px"><span></span><br></p><p style="margin:0px;font-stretch:normal;line-height:normal"><span>Any tips on what to use as a substitute?
