Tube Amp Archive

Thanks! That all makes sense now. Part of me wondered if that were the case, but I was so hung up on it being a mod that I pushed the thought to the side. Thanks again!

Hi, it's been awhile. Haven't fiddled with modding, ect for a long time... Well, I got a Mesa Rectoverb 50 Series 2 recently and decided to open it up and do the series loop mod. And I noticed that somebody pulled a leg of R39 (I think...it says 39 underneath it...could be a value) up and jumped it ...

Hmm, interesting. I may have to mod some of my other dirt boxes.....

After trying one of my MXR Wylde Overdrives at 18 Volts I liked what I heard enough to see if it could handle it without modding. So I ended up finding this: Frank Berdini asks: Can the MXR GT-OD run on 18 volts? JT: Replace power filter capacitor C9 with 100MF, 25V rated part or higher. C9 comes fr...

Similar to a Ceriatone in several aspects. The layout and the schematic are the same as most Wrecks and they are using all modern production parts. They have the same problem as other major manufacturers in that there is no reliable source for significant quantities of vintage tubes or other compon...

Cool, thanks for the replies. I think I may just go ahead and order their kit later on, maybe when I get my Christmas bonus. I know I could save a few bucks if I did a little scrounging, but since it's my first scratch build, it'd be nice to have all the internal parts I need in one kit. I'm going t...

I was doing some research into what transformers to get for the Express build I've started to gather parts for (so far I have a Dirty Dawg chassis and some Flamed Maple for the cab, not much but it's a start), when I stumbled upon this kit from TriodeElectronics.com. http://triodeelectronics.com/twt...

Ordered the pots, caps, resistors and DPDT switches to do the mods to the Marshall. I'll get them done here in the next couple weeks & post up a new thread about it for everybody.

Thanks again for the advice, everybody.

Eminence Texas Heat and Eminence Swamp Thang speakers are my favorite combo, in an "X" pattern in a 4x12.

Ok, thanks guys. I've decided to go ahead and do some more mods to my JVM to get a little more experience, and while I'm at it I'll order the pots, caps, and resistors I need for a TW........ now to decide which one I want to clone...... Oh, and if you're curious about what mods I'm going to do to m...

While I'm thinking about it, has anybody used a breadboard for experimenting with a build before soldering everything to a turret board? Or is that too dangerous to even think about? Lol

ETA: And where's a good place to buy a blank chassis?

I had a look at the Blues Junior Schematic. I don't see any real problem with converting it to a Trainwreck, it is basically just moving circuit blocks around and a component value change. This is the basic idea (YOU need to check). 1)Remove C2 2) shift tone stack to be fed from V1-B pin 8, cut at ...

Thanks, guys. I have been planning on doing some of Bill M's mods to it already, I was just hoping I could add some Trainwreck flavor while I was in there. And I feel comfortable working on amps. Back when I was driving truck, I used to repair my CBs myself and have successfully made a minor mod to ...

Hi, I stumbled onto this site the other day when I was reading up on Trainwreck amps, and today I decided to go ahead and sign up today (great little site here, by the way). My problem is I can't afford a Trainwreck at the moment. So I'm wondering if it's possible to mod my Blues Jr into a Trainwrec...
