kaos, i also use the same method that Robb does, and it works well.
i would add a couple of things to the instructions though.
If you are using a freq counter that has a BNC connector on the front (im pretty sure you are) then you do not want to connect its probe to the antenna jack and key the mic into it.
You will want to pull the driver and final bias wires from their test points first.
this will keep the transistors from amplifying but will allow the small signal through.
yes, you can do the SSB tests with them in place, but i find it easier and safer to just pull them while doing this part of the alignment.
the other thing is that you have to be sure that your 1K tone is actually 1000 KHZ, because if the tone is off freq, your radio will be also.
I think Robb linked you to an online tone that you should be able to trust, but if you are using a tone gen that you built, or is built into one of your pieces of test equipment, you will need to measure its freq using your counter before moving on.
If the tone is off, and you can't adjust it; just compensate for it with your final output freq.
on a side note, mike just posted a video showing a cheap device you can buy that will allow your freq counter to read these low level signals so that you can do the alignment by the book. (both methods result in the same level of accuracy if done right)
