Re: [Bulk] ssb module or atu first?

On the K2, the SSB module is the toughest to build, since the board is more cram-packed than any other. I'd suggest the ATU first, unless you feel up to tackling the SSB module first.

Re: [Bulk] ssb module or atu first?

The only possibly complicated spot in the ssb board is a tiny
surface-mount component, which is itself mounted on a small circuit
board that needs to be literally wired in place. Otherwise, as Bill
says, the packing density is high, but it goes together without trouble.

The ATU is very straightforward, and is moreover a very (extremely)
useful add-on. I found it fun to build. (In fact, the whole K2 +
accessories experience was quite enjoyable -- I built the ATU, the SSB,
the 100 watt unit, and the 10 watt unit
slowly and deliberately, and was delighted with the end product. The
precision with which the units went together was very pleasant compared
to the many Heathkits I built earlier in another life.

The surface mount IC for the KSB2 board is already pre-mounted. No
need to wire it in place.
The only thing that means is that one should handle the board itself in
an anti-static environment.
A wrist strap is good, but the addition of an anti-static mat is great.
Connect the lead on the wrist strap and the mat to the AC safety ground
- assuming you have proper house wiring. Make sure the AC ground is
intact. You can obtain a simple tester for AC receptacles at a hardware
or DIY store.

I agree the ATU is not packed as tightly, but for anyone who has
completed the K2, either can be tackled without major problems - just
follow the instructions (in order) and use good soldering techniques.
