Tube or solid state?
How much do you want to spend?
Bottlehead Crack is a good headphone amp, IMO and has good instructions.
You won't save much by buying a 'kit' vs a built version if you are looking at the cheaper solid state HP amps, and with the 'ready to use' amps you have some warranty protection.
Cruise over to head-fi and you will have reading for weeks...

i'm not entirely qualified to answer the kit or type but i will say that unless you can solder and have a semi decent iron then i would start by learning to solder first. saying that i use a £14 temp adjustable one i got off ebay and it does the job just dandy but i can also weld and braze.
i was told recently to build a cmoy amp as it would help me understand things a bit better. How to Build the CMoy Pocket Amplifier
or you can do this as you don't even need a circuit board DIY Enthusiast Discussion Thread - DIY AMPS, Custom Cables & More - Page 83 - www.hardwarezone.com.sg

If breaking any rules im sorry.Do you see any problems for a newbie in making this it seems straight forward enough

Looks like you should be able to assemble it ok. Get some 63/37 solder (eutectic) and a wet sponge for your iron.
It seems to say that some(?) of the parts are used, that may be why the price is low.

Thank you for quick reply.Why 63/37 solder
This one seems very good and not so many parts

It's the best kind for good electronic solder joints. Don't use the 60/40 type.

I've listened to one of those for years until it recently gave up.
I liked it very much.
For SQ I'd swap to Wima or similar filmcaps where possible ( the smaller caps lets say under 1uF),
I had a 2x15 1A toroidal transformer powering mine.
When it comes to solder, my favorite by far is the 60/38/2 (2% Copper).

I've built several of those. They're quite good for the price but the overall sound quality is quite dependent on your choice of op-amp.
This folded cascode job? Why not.

I don't really like the 75 ohm output impedance though (and who knows whether it's stable without that), unless you just happen to have headphones that appreciate this kind of value, plus I highly doubt you'd get anything even resembling original 2SK170s with a kit like this (there's like a gazillion fakes of these now-rare discontinued devices out there, none of them being remotely close in their characteristics, the only known substitute is the Linear Systems LSK170).

It will be a little bit more involved than a kit you buy ready to mount, but here's another one which I like the schematic of:

More involved because you will have to have PCB made (unless you find someone on that thread with extra to sell), order components, etc...
