Say a fella wants to build an SET monoblock based on the 300B..


Could you point him in the right direction or where to start. I see a kit on ebay but not sure if that's legit or not. I don't own the speakers yet and plan on building my own that would pair up well with the amp. Any help appreciated.  
I heard, and liked, the Elekit amp I heard at several audio shows.  This is supposedly an easy kit to build because the instructions are very clear and easy to follow. Elekit also offers several options for upgraded parts.
In truth  you are much better to let an expert build it .
Radu Tarta has been building SET amps. And DHT preamps 
for many years ,knows many secrets that only an expert  
with tubes would know. And his prices are not that much more then you can build it yourself .there are just so many things that can go wrong . The cost of the chokes ,and transformers  are by far the most expensive part of the build just check his name out in CT .he builds for the Love of the build ,profit  is not his main goal.
he has built many amps,preamps for myself and others .well worth your time to consult with him.
