[TenTec] Re Service Queue

[Phil Chambley, Sr.]

Al et al.....

Those of us to whom changing final transistors has become routine, often 
overlook a small but crucial point when explaining to others just how to 
go about doing it.

After you've removed the old transistors, clean the pads well and make 
sure the sink surface is clean.  Then, after applying compound to the 
transistors, mount them and tighten the screws BEFORE SOLDERING the wings.

If you solder before tightening the screws, you'll likely pop the metal 
sink off the backside of the transistor, and that cannot be repaired.  
So, if you're a fan of MP devices, neither of your new transistors are 
useable and you'll need a new matched pair.

Other than that, it's pretty simple.  You shouldn't be afraid to tackle 
it yourself.
