Low power amp with "THE TONE"

[robertkoa]

Have any of you made a Very low power amp
/preamp with tones like Eric Johnson and Andy Timmons have nowadays? The closest way to approach it is to start with a pure toned Dumble type overdrive since it's easier to make the tone a bit gritty once you have the clear harmonic overdrive.I believe the Dumbles have the most pure (harmonically consonant ) tones in medium gain of all the designs using preamp gain as primary tone enhancer.I'm here as a player NOT an inventor or a tech. Another thing I have wondered about and even talked to Hartley Peavey about in the early nineties is this; have any of you ever seen or used a circuit which had a 12ax7 preamp going to a micro output section like a 12au7 or 12bh7 as a dual stage output section then taken that output section back down to line level and mix back into preamp section to go to the TRUE output section and speakers. So you are using a mini output section as part of the preamp to generate saturation and harmonic distortion for a non volume dependent overdrive and tranny saturation which could create tones possibly smoother and require less filtering than merely cascading 12ax7s. Anybody?

I haven't actually built anything like a low power Dumble but I do have an amp I just completed and brought to market called the Lil Devil. It is two watts and uses subminiature tubes. It is styled after a Trainwreck Express and not a Dumble. I am also working on a adapter to plug into the speaker jack that will allow you to use the amp as a preamp to either go into another bigger power amp or into a mixing console for recording.
You can check out the Lil Devil in this thread

As far as the Line out goes, Ken Fisher uses a line out that developed it's signal from the speaker output of his first Liverpool. This allowed you to get all of the power tube breakup, any coloration produced by the OT and send it to a mixing board like you are describing. Ken built this amp back in 1983. IMHO using a 12ax7 or some other triode tube will not produce the same sound, dynamics compared to a normal output tube like a EL34 or 6L6. Going from a pentode to a triode just doesn't give you the same sonic characteristics as far as I am concerned. I used a pair of 5902 subminiature beam power Pentodes in my small amp and these do sound a lot like their big brothers the EL34 and 6L6.
