    Hey there! I've done this a while back now (last year in fact), but I thought it'd be appreciated here.

    I've had this lovely burgundy Honeytone amp for the longest time, but eventually the circuit in it failed. A while afterwards, I got some subminiature tubes I started playing with, and the thought of putting those inside the Honeytone sparked the begining of this project.

    Here's all pictures and info from the process of making it:

    It was even featured in Hack-A-Day!

    Since then, I've swapped the high-voltage DC-DC converter board for a less noisy and smaller board, and I'm working on putting another subminiature amp inside a Benson AM4 (a cheap clone of the Marshall MS4).

    Fine Job, @blackcorvo ! I dig your HoneyTube ! It's a challenge to enter all that stuff in a so small amp casing ... :cool::cool::cool:

    Is the small speaker worth the transformation ? I mean : is the sound and the power decent with it ?

    This gives me ideas... :twisted: :rolleyes:

    That said, I'm not sure that a standalone circuit (= directly powered by mains) would enter in a such small box o_O... But why not testing it, after all ? Honeytone maps can be found used for cheap... :)

    I made one amp like yours but a bit bigger to be standalone : The RadioTone...

    @blackcorvo,

    Here's the sound of the Radio-Tone with my Squier Std Strat and a touch of EHX Cathedral Reverb :



    I made tests with smaller speakers, but the results were not convincing... What about the speaker of the Honeytone, supposing you re-used it for your Honey Tube ?

    @tubelectron That's an amazing build you did there! The style reminds me of the WEM Westminster (http://www.vintagehofner.co.uk/britamps/watkins/westminster/west26.html) and Clubman amps (http://www.vintagehofner.co.uk/britamps/watkins/clubman/club11.html), which I dig a lot!

    I was originally gonna fit a power transformer inside the Honeytube, but quickly realized the internal space wouldn't allow for it, so I opted for an external 12v DC brick, and a DC-DC step-up board to give me my B+.

    For the Benson amp I originally tried a parallel-single-ended ECL84 output with a 2-stage preamp, but it didn't work out. Hisses and whines like it's asking to be put down :( so what I wanna do next, is maybe doing a mix of a 12AQ5 and subminiature tubes for the preamp.

    I never used submini tubes, I should...

    Do you have a sound sample of your Honey Tube so I can hear how it sounds ?

    It's the first link on the Hack-A-Day article:
    I start with the 8-inch speaker in the background, then I unplug it and use the internal one.
