No problems with it, tested and working. You will need to devise some sort of case, or you could probably use the box I send it in
I used HomeGrownAudio silver wire going to the input and output jacks. A nice, cheap entry into the tube world if you can take 10 minutes to find a cheap case and drill out sockets for the jacks.
This is the improved version that runs off of a single 9V battery+2xAA.
