[Amps] THE SKINNY ON MY AL-82

[Hardy Landskov]

Carl,
I got a real laugh out of that. Thanks.
The point in my email was for people to think about amplifiers, early 
Hallicrafters, WRL, National, etc equipment that they are trying to restore 
or just get working. Take time before plugging the equipment into the wall 
because many times those pieces "will let out the smoke" and then you will 
have a real big problem on your hands.
I recently purchased a Fluke 117--wow-- best DMM I ever had. That DMM has 
been invaluable to trouble shoot radios.
Ok Merry Christmas to all. I have to hit the road.
