Hi All,
Thought I'd share some work I did over the weekend with you DIY Audio enthusiasts. The item is my recently acquired AC ReGenerator Power Inspired AG-1500. The link to the official website is > http://www.powerinspired.com/ag1500-ac-regenerator-1500w-psu-p-1742.html . I got this last week from an SNA member who had got it from another SNA member before.
Just a look through the front grilles & judging by the amount of dust gathered I thought that this has seen at-least a minimum of 2 years work. So I decided that I will take a risk and do a little experimenting in trying to clean it and make it look close to new (Sets my heart & mind at ease knowing that my equipment are all clean).
Just a Caution if any owners want to try this, Removing the cover of a product almost always voids any warranty. And there's obviously a Hazard of an Electrical Shock if you are not careful enough. However, if you have your basic electronic skills & servicing skills, you should be able to properly clean it and put it back together without causing any harm to the device or yourself.
Basic Service Skills needed > Ability to remember how/which cables/parts were connected originally & Put them back properly before plugging back to AC (I usually take pictures) / Skilled enough to leave no additional screws when fixing the parts again 
(We've all done this more than once)
Basic Electronic Skills needed > Know-how to properly drain the residual current inside (I usually disconnect the mains and switch the device on... I know this wont work for some cases, but for this, it was enough) / Carry out the whole operation without damaging any components by mishandling.
So, I started by draining the residual current (as I explained above) and opening the case. what you'll find are the input & output circuits next to the power sockets with the rest of the area covered by a plastic cover held by 3 plastic pins. These pins can be lifted initially by a flat screw driver & then lifted by hand once they come up.
The whole disassembly was pretty easy with the exception of removing the fan controller circuit. This circuit is bolted from within to the same screw that has a philips head on the outside. So you should never use the philips screw first. you have to remove the small bolts (2 bolts for each screw before and after the small fan controller PCB) inside with a pair of nose pliers and then remove the screw with the screw driver. I almost completely damaged the screw head before figuring this out.
Overall I found the whole device to be Extremely well built. When you see the components inside you realise how much of work and how much of a fine finish has been given to each and every component inside. And Now After only 1/2 a day's work, I'm a happy owner of this nice and cleaned unit which gives properly ReGenerated power to all my Equipment.
Cheers
