Save your money and buy a REAL tube amp from Will Vincent (autospec). I have his SE45 amp and it is superb! Need more power? Will can build you a 2A3 or a 6L6/EL34/6550 single-end amp! Beyond these PP is needed for more power: his Dynaco ST70 clones are excellent!
Inexpensive Tube Amps
Anyone have any experience with the following? I want to try one just to see how the sound compares to my Yamaha and Denon solid states. Since the Denon is living on borrowed time I will likely have to replace it this year anyway. Looking at the Nubsound and noted a Germtune that is identical to the Nubsound but costs a bit more. Reviews are largely good including those on other forums.
