Fast shipping, 20 days after my order was made, it arrived! The kit was nicely wrapped and very well taken care of. All inclusive a (Chinese) manual and spec. It seemed a little advertised as a '2N3055' DIY- kit on the leader of the advertisement, but holds infact 3DD15D tubes instead. (if you looked at the pictures of the advertisement, you do see the 3DD15D, so it comes truly 'as shown'!). These tubes are a bit similar, but only capeable of 5 Amps/50 Watts where a 2N3055 handels 15 Amp/115 Watt I will experient a little and have to test which one will sound better. As bigger does not always mean better if it concerns audio... For now very well deserved 5-star rating from me to the seller, for such a serious job. I will review after I have build the kit and tested the mentioned variations and have audiable ratings / results. Thank you seller! :-))))))))))))
