Hello and thanks to everyone who has chimed in on my question. Do I stand a
good chance of getting a decent amp kit from Velleman? I'm not looking for
"high-end" stuff but I also don't want a fire bottle.


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.
