DIY - E65 E66 ASK audio amp IC replacement kit by Paradise

I bought a used ASK (with bad AMP ICs) and installed the diyparadise kit (as I bought two several years ago). Time consuming at several hours, but I did take time to follow the traces and take some pictures. I've tested it for over a week and it sounds good. As long as the supplier doesn't change the wire colors, these photos should be helpful. Note that these photos were with a pre-facelift ASK unit. The circuit board design and traces did change for those built 03/2005 or later (Facelift).

Note: I have a spare diyparadise kit for sale. Send me a PM if interested.

Step 1: remove old ICs (see youtube for video using 200W soldering iron)
Step 2: flip board over and solder last copper pad to 3rd pin with jumper wire
Step 3: solder standby (blue) wire and 8 speaker output wires
Step 4: solder power (black) wire
Step 5: solder 4 line level input wires (either back side of capacitors or bare pads)
Step 6: install board, mark center of holes in AMP IC mounting tab (mount top of tab just under ridge in aluminum chassis)
Step 7: cut middle plastic tab (circle) and drill 2 holes
Step 8: apply heatsink compound to back of new AMP ICs and bolt to aluminum chassis

I ordered the mod part from paradise.
I will soon make a video on how to solder the mod and replace capacitors.
Hope this save alot of headaches for everyone as I can find no such video at the moment....
Peace and love
