    If you like watching vids on people repairing amps check out
    “uncle Doug” on YouTube. He does a really good job troubleshooting and explaining the circuits

    I just got this one.. Loving it so far.

    Anybody built the two stroke amp in it? How did it sound? I can't find any good vids on YT of it.

    I was tempted to build it but it seemed kind of expensive so I built a 5e3 instead for my first build. 10 amps later, and counting....

    Awesome.. you're an experienced pro now. I thought the same thing about the two stroke being expensive. There is a kit on reverb for $400. The regular kit is 600.. funny thing is it comes with an 8" and 10" speaker but no cab.

    I haven't heard anyone playing one that could play very good. I think it may be based on a Princeton but with changeable power tubes. That'd be cool if it sounded good.

    I have learned soooooo much from Uncle Dough and Terry D-labs.

    Our very own Mr. Hopkins has also been a treasure.

    I like them both, Uncle Doug offers a more precise description on what he does, D-Lab is also very good, since he also knows what he is talking about. Essentially they gave me a better understanding on how to work on all my amps.
