4-4-0 [2 NEW BUILDS WITH PICS; THE 2 WATT WRECK]

[GainMaster]

[For those of you that are new to this thread, I built a 2 watt PP Wreck using a 6SN7 for the output section. The final schematic is posted but there is still some final tweaking going on as with all Wrecks. Unlike previous low watt builds, this one is capable of blooming feedback. With the gain on 5, unless you mute the strings of your guitar, it will just slowly roll into feedback. I have tried different pickups with the miniwreck. As far as blooming goes, my SD Distortion pickup works the best. Simply wiggle your finger a bit and you can maintain a note forever.

I'm also working on a new way to apply lettering to faceplates by printing the letters on wood veneer. The initial test was promising. I am planniing to start the lettering this weekend. Thanks for the interest. Here is a link to the schematic. http://www.ax84.com/4-4-0.html This page has the latest version.

I added the clip to the first page so you could find it easier.]

I'm on the verge of starting a new build. It will be a Wreck preamp mated to a 2 watt PP output section using a 6sn7gtb. The head cab is finished and I was thinking about putting a logo on it. I was thinking about calling it a WreckLess since it will be a Wreck less 30 watts. Will putting a WreckLess logo on my head cab cause me any copyright or pattent infringement problems if I am only building one amp for myself?

Thanks
Brian

There's an "Australian Crawl" song called "Reckless"

Hey Brian

I dont know of any legal issues, but then again, I'm not a lawyer.

You'll love the sound of that amp tho - I built a Moonlite which used a 6sl7 phase inverter and a push-pull 6sn7 for an output, and then gutted the preamp and replaced it with the Express preamp.

About 3-4 watts of screaming blowtorch. If I were to do it again, I'd skip the 6sl7 PI and just stick with the wreck 12ax7 PI adjusted however was needed to drive the 6sn7 halves... The 6sl7 seems a bit noisy.

Great. Cliff Chappell and Jon Anderson over at the AX84 site have managed to put together a 12AX7 PI that doesn't slam the 6sn7 as hard but allows the full gain of the PI to shine through. I recently built an October~Studio using the same output section and it cleans up very well with a twist of the guitar's volume if the gains aren't maxed, so it is an excellent cantidate for a Wreck preamp. I've been really looking forward to this build. Thanks for chimeing in.

After the Rocket Group build project starts to taper off, I hope to build a Rocket using PP triodes... I've had great success with PP Triode amps and get some great low volume tone from them...

a couple links for you...

Putting a logo saying WreckLess shouldn't infringe upon anyone's rights, unless there is a company with such a name. If you were taking the normal TrainWreck logo and modifying it to what you want, it could possibly be an infringement, but if it is only for your own amp and you aren't planning on producing them commercially then I cannot see you having any problems. Trademark and Copyright infringement issues usually only come about when there are serious economics at issue, but in the case of an individual doing a one off, any possible gain is far out weighed by the costs of litigation.

But take what I say with a grain of salt, I'm a law student and not a lawyer yet.

That is about what I though too. Might have a problem if I sold it on eBay but shouldn't otherwise. Thanks guys. When I start the build, I'll post a few pics.

Here is a pic of the logo I plan to use

Brian,

Great logo - how do you plan to cut or burn that image into your facepanel?

It is either going on my faceplate or cab. I bought some veneer that matched my cab and faceplate. Figured maple. They are dyed a redish brown and the veneer is undyed and very light colored. I planned to print the logo onto the veneer with a laser printer, glue it to the face plate, then coat it with a few coats of poly. Plan to do the lettering for the knobs and such the same way. Hopefully the logo won't run when I coat it with the poly.

Very Cool - do you want to do a tutorial, that sounds like an awesome technique. I never really thought about running a veneer sheet through a printer - how does that work?

I have made front panels using a laser printer and clear acetate (overhead projector) sheets, but the ink didn't seem to like the poly coat so it got a little tricky, but I didn't work at real hard.

I was thinking just tape the veneer to the paper and run it through the printer. If it works, I'll do a tutorial

you will be fine if it is for your own use.

Cool, I'll check out Cliff's poweramp schemo then, 'cause I always thought about building another one and making that change. Even with some noise issues, I love my hybrid wreck-moonlight; it really sounds like it is on the verge of self destructing and has a great over the top lead tone.

Here is a link to the October ~Studio with the new 2 watt PP output section. http://chappellamps.com/schematics/AX84 ... 080501.pdf

You will notice the 250k resistors after the PI coupling caps and the 82k grid resistors on the 6sn7. These attenuate the 12AX& PI enough to use it with the 6SN7. I plan to use the same output section mated to the Wreck preamp. Should have the amp built in a couple of weeks.
