bly,,

 thanks very much, i've never built an amp before, but i want a valve amp, and this seem's the simple  way to get into building them, just gathering information and reading up on valve amp wiring at the moment, just trying to get my head round it all,

This is a very simple and basic amp.  The hard part is fitting it inside of a small cigar box.  First time builders would be wise to build it into a large box.  This will not only provide easier construction but will provide better performance when it comes to hum and noise.  Parts layout is much more critical in cramped spaces to prevent hum and noise.  For safety reasons, care must be taken when working with high voltages.  Although this amp doesn't have real high voltages, as compared to other higher powered amps,  they can still be lethal.

priced all the component's up and it was cheaper to buy this used amp, a AXL t15r-combo, it's got a tube pre-amp and a solid state power amp, i'm going to pull it to bit's and make a new cab for it and use a 15" speaker i bought, plus i can see how it work's and get a better understanding of tube amp working's, might be able to sell the AXL speaker and cabinet, recoup a bit of money back,

It will always be cheaper to buy a junker amp and convert it into something you want. New parts are expensive especially transformers.  Keep in mind that you will still have a solid state overdrive sound from this amp.  The tube preamp will add some tube like distortion.  It should be a good learning experience for you.  Have fun with it !

yes, i'm halfway there, with the tube pre-amp, wondering if i could convert it from the s/s power amp to valve, as long as it's not going to be too expensive for part's, ?

Depending on what voltages they are running the preamp tubes at you will need to build a high voltage power supply for the power amp.  Probably easier and cheaper to use the SS power amp for this project.  Do you have a schematic for that amp?
