Build your own! The JE Labs 300b has only 24 components total and could easily be put together by a novice, with caution about high voltages. There is a page at angela.com with schematic and some building instructions.

With 4 receivers/amps/integrateds, I haven't been able to justify building one yet myself. Besides, parts alone would cost you a good part of $1000, considerably more than my 1050 and my Dynaco ST70, combined.

As an alternative, look for a local DIY audio meeting. I went to a Bottlehead meeting and heard my speakers powered by an AudioNote 300b amp with Western Electric tubes. Verrrry Sweeet. Funny thing is, everyone preferred the sound of my speakers with my Dynaco. Look here for pics: http://www.uvm.edu/~rboles/audio/ne_bot_may-17-03.html
