[TenTec] Corsair II realignment: DIY?

[Dr. Gerald N. Johnson]

When not going through authorized distributors it is possible to pick up 
counterfeit parts made to emulate good parts or good parts that are old 
or didn't pass inspection. That's most hazardous when you don't have a 
good capacitor checker to inspect the bargain parts. I don't like to use 
electrolytics more than ONE year old when I can read the date code. Some 
have used a private code that's not easy to break.

Yes the distributor gets more money for the good parts, 30 cents to $2 
vs 12 to 65 cents each for the junk.

Remember the PC board is stressed by the unsoldering and soldering and 
if overheated the foil will lift. A good supply of solder wick 3/16 and 
1/4 inch wide is handy to have too. Putting in cheap parts that prove to 
be poor quality can be hard on the PC board.
