    This amp has a fender style preamp (tube) with a class-D power amp. The correct way to do what musicman is trying to do.

    I may be getting an evaluation unit for review.

    Looks interesting

    I would have liked to have heard a demo with a lot less Reverb. A good comparison with the Jazzamp TEN would be nice.

    I think DV Mark tried it too with the 2 Gambale combos. But they never caught fire.

    Interesting...I don't really hear much reverb there, and for the record I usually run my reverb at "off" or "1". Sounds pretty natural to me in the demo!

    Sounds pretty darn good to me.

    Please let us know if you do. I have been looking more information on this amp.

    Henriksen says that it has a 12" inch speaker

    Open back?

    I don't think you can put tubes in a closed box, even just one preamp tube will throw enough heat to require ventilation.

    Good point. Now I just have to get past the looks

    In one of the photos posted on the Henriksen FB page you can see the tube protruding above the control panel in a transparent cover. From that photo it's difficult to see if they also provided ventilation.

    Tubes are as much heating devices as they are diodes and amplification devices. The typical vacuum tube converts 50% of the energy applied to it into electronic "work." (i.e., diode switching or amplification, depending upon the design) The other 50% is emitted as heat into the "room."

    Tube devices thus are open box designs.

    FWIW, the McGowan clip above is not my cuppa, in terms of sound. I like his playing. I would, however, knob-twist to achieve a different tone. There is a heck of a big mid-bass hump going on in the clip. Reminds me of my old FDR with the bass on 7 and the treble on 7.

    It'd be nice to hear some mids, IMO. I'd bet that the amp can do it.

    It might be the speaker? What speaker are they using?

    I think the amp (in prototype form) sounds better here:

    I have not seen a photo showing the back of the new amp. However, I suspect if not open back, they provided a massive heat sink with fins. I suspect they took a few internal temperature measurements before getting this far a long in the design.

    If it's a tube amp, I bet it's open back. You'd need a coolant loop, otherwise. Fins wouldn't be enough.

    So do we know anything about the actual circuitry? What tubes used? What blend of tubes and SS? Digital reverb?

    Just a guess...Fender tube preamp/tone stack and a Henriksen solid-state power amp. I'm apt to be wrong.

    Isn't this an option with the Mambo amps?

    no, the mambo uses a SS design with a tone stack similar to a BF fender but it's not an actual tube circuit.

    And no , fins do not work without ventilation, particularly in a closed space.

    And yes, it's tube preamp. I have spoken to the engineer.

    So this is a hybrid design melding the classic Fender tone with the weight and power advantages of Class D?

    i think so based on the conversations I've had.
