TrainWreck Express Building

Post by Benetton » Fri Mar 21, 2014 12:29 am

I'll start riding an trainwreck express, and I wonder if this list is updated and correct materials so that I can follow it in the purchase of items. Thank you for listening!

These documents have not been updated for a couple years, mainly because there appeared to be consensus that they were nearly 100% accurate based on known Wrecks. The BOM probably should be updated as prices and parts availability have surely changed in the past years. But, I don't have the time for it these days and it still serves as a good guide on parts.

Hey!

Hi!

I'm going to build that amp. And I will update all prices and availability of parts!

But before, I need to know something. I want my Trainwreck express to work on 6V6 because I've heard that it is better for small venue. I need an amp not TOO loud.

Thanks!

6v6's aren't going to make it much lower in volume. It will however break up a lot sooner. I prefer EL34's myself but that's me. Use an attenuator to lower the volume to usable levels.

Forum Member Sliberty has also used a shared cathode on V1 and a 12AU7 very successfully to lower some gain but he also uses 34's IIRC

Hi!

Okay thanks for the info. There's a VVR in that build right? What do you think about a VVR on it, it should drop volume..

VVR or PPIMV ?

The VVR is very good at dropping volume. You won't need an attenuator with a VVR. It is really a matter of taste. Some like the VVR better and some like the Airbrake.....and some like the master volume best. You need to try all of them to know which you are going to prefer

Personally I use an Airbrake BUT I don't use it to the point of bedroom levels. IMO if I can't move that much air I may as well use a headphone amp or a POD

Okay! Thanks!

I'll need to make some reading about VVR and PPIMV ;)!

Thanks!

This is supposed to be a thread dedicated to Express documents - not searches for parts or build support. There are other parts of the forum for that.

+1

It would be nice if a mod could remove this stuff so that it doesn't contaminate this sticky forever.

Thanks you!!!
I wanna thank all you guys, for your support, stuff, files and more. Just this evening I've finished my brand new express, it works from the first power on.
This results are due to you in this forum. Layouts are great, simple and easy to understand. Thank a lot, appreciated

I'll throw him a bone..

The Mallory TC series are not that plentiful and stoopidly expensive. RJ Guitars was selling some a while back. Personally, I'd use F&T if I built another one.

The other smaller caps can be substituted with similar Mallory caps. Or try something else for flavor. These were chosen as reasonable subs for what Ken used, they are not gospel.

For the MOV, just find a similar variant, again, not gospel.
