Tube Kits
Each kit is aimed towards a certain public , some are exotic and offer unmatched performance and some are "just" high end performers that are jewels in theire price range , and others are aimed for beginners or people on a tight budget but all are build and designed to perform at theire best ,containing the best components available at the price targeted , if necessary they will also include some exotic (expensive) components but we judge with oure ears .If it doesn't really sound better we will choose the cheaper solution .
Have fun building and may you enjoy your kit for a long long time
But allways remember these are lethal voltages that you are dealing with and ,You should always take the necessary security measures for yourself and Others that might use it .

Velleman PP EL34 K4040 :
This is a very popular kit , we just sell it , we also supply an upgrade kit
We do not really recommend it but its high power for a low price with a nice
housing .
Velleman PP monoblok KT88 :
The KT88 is a very dynamic tube and even, Velleman has a mananged to make a
good amp with very cheap components
Using all the components from K4040 ( transformers are identical)
Also other velleman kits available .
