Why the heck would I NOT want to build this???

I love the clean sound from my AX84.com Simple Preamp/20Watt Push-Pull amplifier that I built...

I love the "classic rock" crunch of my 18watt.com Lite IIb that I built...

So... why in the heck would I NOT want to build them BOTH into the SAME AMP so I would not have to lug two amps and two speaker cabinets around and subject my soundman to miking-up two cabinets???

I am discussing this design at AX84.com here.

Crude block diagram...




I would love to hear your comments in the discussion at AX84.com or leave a comment here!!!

One thing I need to work out is how to get them both going at the same time and still include the reverb/effects. I don't think it's as simple as just replacing the 3PDT with a 3P3T switch, but it's getting late and I need to think on it later...

After some discussion, here is version 0.1a...

Marshall 18 Watt build

...Placeholder for my 18Watt build...

Over at www.18watt.com, there are a few designs of the old Marshall 18watters they put out in the 1960's. These things sound pretty freakishly amazing, as does mine.

I built the "Lite IIb" version with tube rectification and a VVR (variable voltage regulation) unit that I originally bought for my TC15 (see post below) but I never installed it in that amp.

This amp sounds absolutely fantastic and it really nails that early Marshall crunch sound. Does that "classic rock" sound REALLY well.

Uses a pair of EL84 output tubes and Classic Tone power and output transformers.

The "Simple20"

...Placeholder for my third amp build...

The pre-amp is the Simple Preamp from AX84.com and the power amp section is the 20 watt push-pull also from AX84.com.

This amp sounds amazing! Really nails that "Fender Clean" and overdrive - think Deluxe Reverb.

I used JJ 6V6 output tubes and Edcor power and output transformers.

This is my "main amp" that I use on-stage with Sonhouse Blues Band.
