Glad to see I'm not the only one who has fallen foul of poor tools. I have all the tools less a Fluke and actual solder station. My Father in Law may have a Fluke, if not I'll pick up one used, and a good soldering station I'll be able to buy no problem. Can't wait for Christmas now.

I will say this, as much as it might be tempting to wander from the original design to satisfy your creative needs, stay the course. When all is done, then additions or variance can be made.

David,
I know that the Salomon soldering stations are fairly popular in the UK and I had one and liked it a lot. Alsothe Hakko fx-888 is a really nice station for not a ton of money.
Welcome aboard, and just be forewarned, the sound you'll get will be somewhat shocking in how good it is, and more importantly, this can easily turn into an addiction
.
There are a number of bottleheads in England and Scotland here on this forum, so hopefully they'll chime in with more parts sources that will be more useful to you.
Welcome again,
Jim

I have found the following article on meters useful and I use the multiple cheap meters approach when testing. I admit I get scared when testing amps, particularly powering up the first time.

Thanks so much guys for all the replies. 
Just wondering if the Crack will be OK with my new headphones? They're Grado 225i's. I just got them in the mail today from the States, and, WOW they're amazing. Currently I'm running them just from my MacBook using lossless files. My plan is to add the Crack, and a USB DAC. Already I'm hooked though!
I used to have an amazing Hi-Fi rig that I had to sell. I felt the easiest way to get close to my music again was with a good headphone rig, and you know what? I think I'm right 8)

David,
Well, there are a few things you can do to the crack to get it to perform a bit better with low impedance cans -- like increasing the size of the coupling caps and a change to the charging resistors, but some folks with more experience with that should chime in as I've never done that. There are a few folks using Crack with low impedance cans, it's just mot optimum and high impedance cans will just perform much better -- think 250-600 ohms, with probably most of us using something around 300 ohms(sennheisers, beyers, etc.)
Hope this helps,
Jim

You might start a new thread headed Crack with low impedance headphones. That would give others with the same problem a place to find the information.

I'll second that bit about checking your work. When I built one of Pete Millett's headphone amps from scratch, after I'd made the last solder joint I didn't fire it up -- I deliberately stopped. The next day I started with the AC plug and checked _everything_ against the schematic. Every wire, every pin, every everything. Even tho I'd been very careful in assembly, I found I'd polarized both output caps backwards, and both MOSFETs were upside-down-backwards. The problem of course is that whn you finish a project you get _physically excited and impatient_, and that's really what makes the sparks fly. But since you're an engineer, I'm sure you know not to fall into that trap.
