    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.

    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!

    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.

    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?

    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?

    American parts and labor are costly. The same is true of German parts and labor. Henriksen, Acoustic Image and AER amps are not cheap. Neither are Cadillacs, Lincolns or BMW's.

    Peter just emailed me back. They plan keep the discount price for a couple of months. He said they are doing the same thing they did for the Bud. I guess they want to get a feel for how it is received.

    IMHO I was thinking this design is geared towards a younger tube amp crowd. 12" speaker, 28 pounds, esthetics, and the statement "Not only for Jazz". Plus the controls look like they are from an alien space craft. And the "hemp" speaker. Should be a disclaimer;"Do not smoke the speaker."

    Maybe it's weak willpower today from lack of sleep, but I am interested. Can I justify making my Henriksen/Sound Island Alfresco my living room amp? It has been recently anyways. And this Forte is lighter than my Alfresco. Hmmm...

    I will revisit after 100 hours of practice and learning two new tunes.

    Correct me if I'm wrong. That's the top of a 12ax7 preamp tube sticking up through the control panel, wearing a fancy hat/tube protector deeley, right?

    Also, note the open back. That's going to give the Forte a different tonal response than the closed-back design, for sure.

    This amp could give Henriksen an entree into the market that Quilter is working--i.e., the solid-state, Fenderish amp market.

    Usually TMB controls are before the gain stage (somewhere in the preamp stage) and EQ is after the preamp and before the power amp. Not sure if this is the case with this amp.

    It looks like an oscillation over-thruster that bends gravity and reduces the amps weight but it's just a good old, stone age tube inside.

    So what, precisely, is an "analog power amp?" I know tube amp, and I know solid-state, but "analog" is normally contrasted with "digital" so I am not sure what an analog power amp is.

    But I don't know much about amp innards to start with, so someone please clue me in.

    The term may be used in contrast to Class D amplifiers (digital amplification), though I would imagine class D guitar ampliers are rare to none-existent in the first place.

    Class D is not exactly "digital".

    You might be right. I heard digital amps referred to as class D but that might not be very accurate. Although that's what people mean when they say digital amp I believe.

    So an analog power amp would receive the signal as an analog audio signal and out put it as the same. No conversion to/from digital? I never even knew amps were converting between analog and digital in the first place...

    I'm not an expert, but an amplifier is something that amplifies sound and they're analog by nature. Some of them might have a DAC (digital to analog converter) incorporated, like a modelling device. But the amplification part is always analog, I believe - and the Henriksen iis for sure an all analog amp, with the exception of the reverb chip (which must have DACs, of course).

    A true digital amplifier is one in which the signal is converted into a digital signal, increased via digital signal processing, and then converted back to analog so it can be passed to a speaker. SFAIK, no guitar amps actually are this. Rather, people get confused by the nomenclature and call (some) class D amps "digital".

    Class D means the amp's output transistors are acting as (extremely fast) switches, as opposed to continuously operating/varying gain devices (typically, class A or AB; google that if you really want to know). The switching in class D can be controlled by either analog or digital circuitry, but the signal itself remains analog. Class D amps with good audio quality were made practical by relatively recent advances in transistors and control-circuitry. Long story short, they can be made much smaller and lighter and operate more efficiently and at lower temperatures than A or AB, which makes tiny, powerful amps a real possibility. The raft of very small, very powerful guitar amps that has hit the market over the last several years are Class D.

    When I hear the term digital amp, I always think they are referring to complete combo amp with DSP (Digital Signal Processing) chips in the design. (or other digital components) not necessarily anything specific to the power amp.
