   Hi,   
   a friend of mine built the k4040 some years ago.   
   The kit has a few drawbacks and shortcomings like an almost inacessible   
   mains fuse that blows quite often when you skip the standby position on   
   the mains switch. The Bias adjustment circuit is questionable, but the   
   potentiometers used are very reliable. Still, should they ever fail for   
   whatever reason the el34 and output transformer might be damaged.   
   You may want to modify the phase spliter to reduce distortion.   
      
   On the other hand the stock kit sounds just fine and i think it is worth   
   buying.
