4. Safety Instructions for AssemblyBasic electrical engineering knowledge is required to assemble the amplifier kit, including experience handling high voltage and the ability to read circuit diagrams and properly use measuring instruments.
Before beginning assembly, you must:
- Carefully read and understand all safety instructions and the provided circuit and layout diagrams.
- Ensure a well-ventilated, dry workspace free from flammable materials.
- Use the correct tools for assembly.
The completed tube guitar amplifier may only be put into operation after a comprehensive inspection of all electrical connections has been carried out and compliance with safety regulations has been confirmed. Any modifications to the kit or use of components outside the specified parameters are not permitted and may compromise the safety of the device as well as void the warranty.
Before operation, all components, assemblies, or devices must be securely installed in a housing to prevent contact with live parts. Additionally, ensure that all components are disconnected from power during installation. All live cables and wires connected to the device must be checked for insulation damage and breaks. If defects are found, the device must be taken out of operation immediately and may only be used again after the defective wiring has been replaced.
5. Important Notes on Soldering and AssemblyGreat care must be taken when soldering and wiring. Avoid using acid-containing solder or soldering grease to prevent cold solder joints or poor connections. Such defects can result in extensive troubleshooting and may even damage components.
Careful and precise assembly significantly reduces the likelihood of malfunctions.
Double-check every connection and each step. Follow the instructions exactly and do not skip any steps.
Use a small soldering iron with a maximum power of 30 watts. A clean, non-oxidized soldering tip is essential to ensure effective heat transfer. Perform soldering quickly to avoid damaging components, and do not move the soldered component for several seconds to ensure a stable connection.
After each soldering process, clean the soldering tip of excess solder and dirt to maintain solder joint quality. Also trim the component leads directly above the solder joints.
After installing all components, verify that they are correctly positioned and aligned. Ensure that no unintended short circuits are caused by excess solder, as these may lead to malfunctions and damage.
Please note that errors caused by improper solder joints, incorrect wiring, or improper handling are outside our responsibility. Thorough workmanship minimizes the effort required for troubleshooting.
Basic knowledge of electronics and experience handling electronic components and soldering techniques are required for successful assembly.
Persons assembling a kit or completing it through modifications are considered manufacturers in accordance with DIN VDE 0869 and must include all relevant documentation and personal contact details when transferring the device to others. Kit-based custom builds must comply with the safety standards of industrial products.
If you are uncertain about electrical specifications, external circuits, or connecting additional components, consult a qualified professional. Before operation, the suitability of the device for its intended application must be verified. If in doubt, contact qualified personnel or the component manufacturers.
Our customer service is available to assist with assembly questions or uncertainties. Your safety and compliance with product safety regulations are our highest priority.

- Ronny H., 02/22/2019This is a really nice design. I added a mid control to the circuit to be able to fine tune the EQ a little more. Besides putting in a ECC99, I also switched V1(12AX7) to a 5751. This gave a little more headroom and great harmonics. Perfekt for blues and rock. Very pleased with the sound. /Ronny Hogland also switched V1(12AX7) to a 5751.

go to post - Joel C., 07/03/2017I bought this kit as a basis for future modifications for my trials... but after trying it (with ECC99), I totally dig the sound and feel of the amp: very responsive, with a surprisingly good smooth clean sound when rolling back guitar volume and a great sustaining and singing distortion at higher gains! But beware, with ECC99 (recommended tube: great tone) it is pretty loud, even with a master volume. In the end, I will just keep it as it is and build a nice encloser for it; it is too good to tinker with its circuit;-) Dirk did a really good job at designing this lower power version of the Trainwreck style amps, and all components are of very high quality. The modular approach with separate power supply PCB helps to build it quite fast and check your build step by step. If you are a beginner, just read very carefully the diagrams and indications: everything is there but this require some concentration to follow. Now for my experimentations, I think I will go for a scratch build, because if all other LoW TubeTown amps are as good as this one, I will always keep them in their original form and not care moding them ;-) very responsive, with a surprisingly good smooth clean sound when rolling back guitar volume and a great sustaining and singing distortion at higher gains!

go to post - Sergey S., 11/14/2016Great little amp. I dont have the Trainwreck to compare with but from what I heard on Youtube the sound tends to be close to the original. I did not have any difficulties with the kit, even though it was my first amp that I fully assembled myself - the layout on the forum page is sufficiently explicit. I did't like that much the veroboard. It is quite small and if you want to use, let's say, different kind of resistors like RN65D, they may not fit. But that's not really a problem. All the parts provided are of a good quality. And besides that is why the amp is relatively small. I put a ECC99 tube and it is veeery loud ) Overall impressions: really good sounding amp for such a small price! have any difficulties with the kit, even though it was my first amp that I fully assembled myself - the layout on the forum page is sufficiently explicit.

Built it as my first project, and it worked perfectly on the first power-up!
Sounds great with my two guitars:
Japanese Strat with Duncan SSL-1 pickups
Japanese LP Custom with Duncan SH-1 and SH-4 pickups
I've also used a reactive load with a speaker sim—can't wait to try it with a real speaker!
Advice for New Amp Builders:
???? Measure all parts before soldering them onto the board.
???? Write down all measurement results for each component.
???? Only solder parts after placing all of them on the board.
???? Take your time—do anything only when you're 100% sure of what you're doing.
????Watch carefully pictures provided on project page, they're really helpful.
It'll pay off 200%!
Good luck! ???????? /> Japanese Strat with Duncan SSL-1 pickups
